Title: [SOLVED]memory leak in aswmon2.sys?
Post by: BarbaBookie on June 30, 2012, 07:55:50 AM
there is a memory leak in nMvA pool tag. running findstr /m /l tag *.sys resolves it as aswmon2.sys or aswmon.sys.

there is a memory leak in nMvA pool tag. running findstr /m /l tag *.sys resolves it as aswmon2.sys or aswmon.sys.

I can absolutely confirm this under Windows XP SP3.
Using the methods described here (http://blogs.msdn.com/b/ntdebugging/archive/2006/12/18/understanding-pool-consumption-and-event-id_3a00_--2020-or-2019.aspx), here (http://support.microsoft.com/kb/177415) and here (http://support.microsoft.com/kb/298102), I'm getting

Not to thread Hijack, but I'd like to know if this may be affecting me too. 

Windows XP  SP3  Avast version 7.0.1451

I lack an programs to find memory leaks, but I've noticed that my Commit charge is growing at a very fast rate!  Generally, with firefox running it averages 350-400 commit charge...I'm over 550 now.

Also, when I turned on my monitor after leaving my computer on all night, I noticed I was logged out of Skype, the skype screen was entirely black save the drop down and login info.  Half the names on Trillian were blank or missing letters, my desktop had multiple icons blacked out and I could do nothing except start menu - restart.  When I did, I noticed a popup beneath the busted skype window saying "There is not enough memory to complete this operation."

Well ,I'm a little more reassured about my (memory leak?) problem like have more and more guys with WXP SP3 and new version ais 7.0.1451

After 2 or 3 hours (with browser activity) , popups appear to say programs didn't be found , not enough memory , .... some others programs closed , windows half blank , icons blacked

So , pending an update or a solution , where/how can I downgrade ais to version 7.0.1426 , please ?

Thanks

1. Uninstall avast from Control Panel first.
2. Boot.
3. Use Avast Uninstall for complete uninstallation.
4. Boot.
5. Stay off-line (not connected to Internet)
6. Install again the old version: http://filehippo.com/download_avast_antivirus/ or http://www.oldapps.com/avast_antivirus.php?old_avast=6918
7. Boot.
8. Register avast (insert the registration key).
9. Uncheck the programs updates (set to manual).
10. Only then connect to Internet (go on-line).
11. Check and post the results.

Well , all right with 7.0.1426 (total memory kernel = 85 000 ko , it was to 400 000 ko when crash with 7.0.1451)

I am having the exact same symptoms listed by the users above.  Really hoping this critical error will be fixed asap as it renders my computer unuseable after a few hours (parts of gui missing, error messages, programs unable to start - fixed with a reboot until memory runs out again).  Also using WinXP SP3.

Ditto for me! I'm suffering exactly the same symptoms with 7.0.1451 and WinXP Pro + SP3.
I did what Tech suggested and downgraded to version 7.0.1426. Now I'm back to a working avast!Pro again.

Suggestion: avast should perform a better betatest phase... I already learned such horror stories with e.g. ESET NOD32 (the reason why I switched to avast, they never fixed it)...  :(  :o

An update to the .1451 update is severely needed, and in a hurry!  >:(

I don't appear to be suffering the issues on my XP Pro SP3 system that others are reporting here, not that means they aren't which is clearly the case.

Whilst I don't have the memory leak tools to check it in the way that others have done, only the task manager data on usage and I'm not seeing anything overly different to normal, running out of memory and no errors as mentioned by others.

The memory leaks described above appear in the kernel memory pool, which is not visible in task manager!

You have to use at least Process Explorer's "System Information". There it shows as "Kernel Memory".

Post by: DavidR on July 01, 2012, 06:47:13 PM
Whilst that is true, but the consuming of your memory resulting in memory errors is a very rough and ready indication if you have the problem.

I have received some information on this:
By all accounts this is only present in win2k/winXP and I'm told the bug is fixed (and relates to rename operations). Now I don't know if that fix, means an internal program build awaiting release, I have asked that and awaiting confirmation.

Like I said before with v7.0.1451 Kernel memory grow to 400 000 ko , now no more than 85 000 ko (1 day opened with v7.0.1426) . (Win xp INTEL PIV hypethreading)

On the other hand , for my 2nd Pc (win xp AMD Athlon) , no trouble anymore with new update . It confirm it's not a general problem.

DavidR, +1

Seems if some of those who wish to run systems 24/7 are the ones experiencing this problem.

XP Pro SP3 Avast! 7.0.1451 2GB RAM no problems seen so far, but then again only run system when actually using it.

Great thread!  Great diagnostics.  Should be a standard part of the beta testing process, it is likely those who have lesser memory (256-512 MB) might display this issue sooner, rather than later.

@ Herrminator,

Is problem now resolved?  It was an update that fixed it?
Title: Re: memory leak in aswmon2.sys?
Post by: DavidR on July 01, 2012, 08:04:43 PM
Well not really, given what was said about the bug being related to rename operations, so those with a high number of these rename operations (no idea exactly what that may entail, P2P, Torrents, etc.) would see this in a much shorter time frame.

@ DavidR,
It is the rename operations, so a torrent program could cause this issue?  Care to explain (You do not have to)?

If so, this is why only some users have this issue?
Title: Re: memory leak in aswmon2.sys?
Post by: DavidR on July 01, 2012, 08:21:17 PM
It isn't something I use P2P, but Multiple small parts of a big file may well (I don't know) if that would somehow incur rename operations in the way avast would have to scan the multiple parts.

I upgraded to 7.0.1451 on three computers. The one with Windows 7 has been running fine, but the ones with XP SP3 have been experiencing problems.

After awhile my computer slows down to a crawl and then I get an error whenever I try to open something. In the event viewer these are listed as Event 26 and say "Application popup: taskmgr.exe - Application Error : The application failed to initialize properly (0xc000012d). Click on OK to terminate the application" or "Bad Image... is not a valid windows image. Please check this against your installation diskette". Other things also happen like the letters on the Start button disappearing, labels on the top of windows disappearing or turning black, and the shut down screen is changed. After a reboot things go back to normal until the problem happens again (usually in a few hours).

The event viewer will sometimes also show SidebySide errors (Event 59) at the same time these problems are happening. They say different things but for example one says "Resolve partial assembly for Microsoft.Windows.Common.Controls. Reference error message: Insufficient system resources exist to complete the requested service."

These errors seem to be triggered when copying/moving a lot of files or browsing the internet w/ a few resource intensive tabs.

These problems started happening immediately after getting the new upgrade in Avast.

Well, that's when it shows. On my machine, there seems to be a fixed pool of 356M (sic!) paged kernel pool and it filled up slowly with 7.0.1451.
My machine is running 24/7, it's a kind of family server.

@ Herrminator,
Is problem now resolved?  It was an update that fixed it?

Resolved? Not really. I downgraded to 7.0.1426. That helped.

@DavidR:
Whilst that is true, but the consuming of your memory resulting in memory errors is a very rough and ready indication if you have the problem.

Unfortunately, with this problem, it is no indication. My regular memory use did not go up.
It was only after I googled the Event ID 2020 problems, that I found hints to the kernel pool and methods to analyze it (see the three links in http://forum.avast.com/index.php?topic=100359.msg801837#msg801837).

They told me here http://forum.avast.com/index.php?topic=100247.msg802509#msg802509, that this is a known problem.
It's related to your TMP-directory being on a different drive than your Avast!-installation :(

Glad I've found this thread, having the same problems on my XP/SP3 system
W7/32bit & W7/64bit system are fine.

My XP system runs continuously, I use it as a FTP server and a few other things.
After around 4 hours of running things start failing with "Insufficient system resources exist to complete the requested service" errors and program files not found.

I'll go back to the previous version and await a fix.

Perhaps the rename theory is correct. You could try to batch rename the content of a folder. Another possibility is to download a heap of files. The files will be renamed after download completion, no matter if you use a download manager or not.
I can't check it because I reverted to v1426

Guessing here (may be very wide of the mark) but, by chance, any user here reporting problems using P2P programs?

I personally do not care for P2P programs as I have seen some of them attempt to open literally thousands of Internet connections even, just when booting up, from a cold start.  Limewire is an example.  Never going on my system.

How would I know where my system was going, and how would I be able to stay on top of it?   ???

I had problems moving files like pictures, music or movies.  Another time while installing GIMP. And other times I've had it happen while listening to music with Foobar  + browsing the web with multiple tabs open.

I uninstalled Avast and reinstalled w/ 7.0.1426. So far so good.

Title: Re: memory leak in aswmon2.sys?
Post by: DavidR on July 02, 2012, 02:09:46 AM
The P2P usage is an assumption not a certainty, just a though that P2P apps may result in greater rename operations. But my understanding of what windows rename operations entail exactly aren't up to much. Even searches on rename operations returns many hits but not much clarity.

Ahhhhh!  Well, then this seems to confirm MY suspicion as well.
I barely installed 7.0.1451 I believe yesterday ...
And today I got 2 very weird, uncharacteristic Opera Browser Lockups.
And on both occasions, I couldn't even get Task Manager up to close Opera.  I just barely managed to be able to Reboot via the Start Button.  Somewhere in there, I did get 2 messages of "Not enough System Resources to complete this operation" or something along those lines.

Then while Rebooting, even the various Windows screens looked completely different, unlike what I had ever seen before.
Instead of displaying a full screen blue screen indicating that "Windows is Shutting Down," just a very small window came up to indicate this.

I did vaguely suspect the 7.0.1451 version of avast, but went ahead and reinstalled Opera.
But, after seeing this thread, I am more convinced something is wrong with 7.0.1451.

I'm running WinXP SP2 with 2GB of RAM and I'm experiencing the memory problem and "insane" pop-up messages just 1/2 hour after each rebooting, expecially when using Outlook express.
I was thinking my HD was near to dead...
Or maybe a virus...
No: if my PC doesn't work any more it's only thanks to Avast!

Will a fix really arrive in few days?
Or I'd better uninstall?

Post by: Chim on July 02, 2012, 02:28:06 AM
Actually, I wound up having to completely Shut Down my computer because even that 2nd Reboot didn't really clear up the problem.
I might have to downgrade to 7.0.1426 if this happens again.
Cuz my HP Pavilion doesn't have hardly any System Resources to begin with.  It certainly can't afford to have 7.0.1451 getting out of control and hogging the System Resources.

I think it is time to admit that the new version was released without proper testing.
There are several serious bugs. Just look at the topics. Memory leak makes XP useless. There are problems with Outlook, and many users have problems with definition updating. I would find it appropriate if Avast withdraw this version so the users don't get it by automatic update.

The P2P usage is an assumption not a certainty

I don't use any P2P programs, but there's several batch-backup jobs running in the night.
Some of them do rename whole directory trees, all of them do a lot of copying...

As I said the P2P suggestion was a bit of a SWAG (Scientific Wild Assed Guess), but yes your batch backup jobs could result in a lot of rename operations. I certainly don't have anything like that going on on my XP system. Other than my weekly drive imaging software backup, but that shouldn't cause much in the way of rename operations as the backup creates one image file of each partition on my primary hard disk to my secondary drive.

My computer locked up again yesterday evening for the 3rd time in Sunday alone.
Again, I got one of those messages of "Insufficient System Resources" and had to crawl into just being able to reboot.

So, I'm now back down to 7.0.1426.

Hi There! I also had a massive problem with a memory leak too. I only have a little eMachines EL-1600 that has only 1 GB ram, a 1.6GHz Intel Atom 230 and up to 256MB ram is shared and used for graphics. It's a gutless little "net top". However, with version 1426 I had no problems whatsoever. At the moment I've switched back to AVG Free 2012 which is OK, but that' about it - it's OK. Better than MS SE, but nowhere near as powerful or as good as Avast. I has the same dissapearing fonts and "out of memory" messages that the others have described. This little machine is running Win XP SP3.  I'll keep checking back to see when this memory leak issue is resolved.

One thing I really miss is the real time protection that Avast has, as well as the boot-time scan. AVG has neither in their free version.  Please email me as soon as this issue has been resolved. The reason I updated to version 7.0.1451 is because 7.0.1426 stated that the program as "out of date".  Thanks.

(SWAG), that's good.   :D

Just trying to do some thinking outside the box, as some programs installed or tasks run that Avast! may not be able to handle correctly, like Outlook, Chrome, memory leaks, emergency updater functions, etc.

Software configuration of everyone's system is always different, some better, some worse.  Nothing is standardized, that's for sure.

I think I'm in the same boat as you guys. I'm running XP SP3, I upgraded Avast to 7.0.1451 the other day, and my system has been having problems.

After a while I start to lose text on the screen - where text should be it appears blank. Then if I try to call up Task Manager using ctrl-alt-delete the screen goes blue except for a Windows XP box giving me a few options such as shutting down or logging off.  I get error messages, though I can't always read what they say.

I was worrying that this was a virus, but now I think it may be a memory leak caused by my Avast update. Can anyone tell me if what I have described sounds familiar?

Don't waste time on it, it doesn't work on XP. Install the previous version.

I do agree...

I'm far to be an expert, but I can't help but wonder whether Windows 8 could be the "culprit" for all this mess? I mean, it's supposed to be so different compared to XP and 7 (or is it just it's GUI that's different?)

Windows 8 is a major update, Win 7 not so much, Vista was a major update, XP was minor in comparison, Win 2000 major, so...   Historically this is the release pattern Microsoft has followed.

XP is getting long in the tooth, as the basic os really has not changed since release in 2000, support for SP has ceased, and as time progresses, Microsoft will support it less and less.  Microsoft will not support this os after April 8. 2014.

For example, support for SATA hard drives was never included in SP3.

http://www.microsoft.com/en-us/windows/endofsupport.aspx (http://www.microsoft.com/en-us/windows/endofsupport.aspx)

This means all security updates will end, and as the cutoff date approaches, less and less work will be done to update it.

So yes, Win 8 is the focus right now, and XP is looking at diminishing returns.  Where Avast! devs come in, is the work necessary to work with an older os and also work with the newest.  Twelve years is a long time to support any os, yet Avast! is still supporting Win 2000.  So they are choosing to support quite a few os's from Microsoft.

EDIT:  As this is a little off-topic, I will leave this alone and say no more.

If you want to advertise any particular Microsoft product, I suggest you find another place to do it. This topic is started by a few posters who did an excellent research.
There is still no fix from Avast who released a product that don't work on XP, which in april this year was installed on 25,86 of the worlds pc's.
Please keep this topic on track so a quick fix can be made, and the users do not start new posts about the same bug, because the posts end up with non-relevant stuff.

Avast Free 7.0.1451 works well on my WinXP Pro SP3.  It just doesn't work for you, and some others. ::)

I uninstalled 7.0.1451 and tried to re-install 6.0.1367 but ran into a problem: Setup Selfextract popped up a dialogue box informing me I was trying to use an old version of avast!setup, and that it would download and use latest setup from the internet instead. It didn't give me any other options. Since I was offline at this point it couldn't do that, but refused to go any further. So I was forced to go  back to 7.0.1451 to have virus protection, buggy as it is.

What did I do wrong?

Man, you are testing it right now!  ;D

Yeah, all XP users have suddently become beta testers. But opposite to the previous beta testers, it completely screws up our pc's. The official beta testers seems only in rare occations to be affected by this major bug.

As for the memory leak issue, I had tried the RC1 as well,  but indeed only for a couple of days before the official program upgrade came out. So no chances for me to test it thoroughly.

I upgraded to 7.0.1451 on three computers. The one with Windows 7 has been running fine, but the ones with XP SP3 have been experiencing problems.

After awhile my computer slows down to a crawl and then I get an error whenever I try to open something. In the event viewer these are listed as Event 26 and say "Application popup: taskmgr.exe - Application Error : The application failed to initialize properly (0xc000012d). Click on OK to terminate the application" or "Bad Image... is not a valid windows image. Please check this against your installation diskette". Other things also happen like the letters on the Start button disappearing, labels on the top of windows disappearing or turning black, and the shut down screen is changed. After a reboot things go back to normal until the problem happens again (usually in a few hours).

The event viewer will sometimes also show SidebySide errors (Event 59) at the same time these problems are happening. They say different things but for example one says "Resolve partial assembly for Microsoft.Windows.Common.Controls. Reference error message: Insufficient system resources exist to complete the requested service."

These errors seem to be triggered when copying/moving a lot of files or browsing the internet w/ a few resource intensive tabs.

These problems started happening immediately after getting the new upgrade in Avast.

I have this same issue with Win XP SP3.   Do I upgrade to the latest version 7.0.1456 now? Or downgrade to the 1426? I am completely confused.  I know NOW that a number of items I had saved on my desktop are completely garbled  - I don't even know what they are now.  I had a few documents saved there for easy email attachment but I don't know what is what.
(http://www.angelfire.com/alt2/jerrodsl22/whatisthis.jpg)

So, can someone tell me what to do?  I REALLY like avast and I don't want to quit using it, but I can't do a thing when it acts up like this! And I am on this thing 24/7 almost.

Yes upgrade to 7.0.1456, as BarbaBookie remarked two posts above yours.

Why ?

If because of your other post:
Quote from: zaezd
I renewed the program. My system AMD1600/768RAM/WindowsXP SP3. After updating there were problems. UAC causes a critical error.

I beg pardon for my bad English.

As has been mentioned XP SP3 doesn't have UAC (User Access Control), that only came with Vista onwards.

Thanks for the quick reply.  Done and rebooted. 

Now, any ideas what I can about the garbeldy-gook files? I imagine they are just lost?

Post by: DavidR on July 04, 2012, 03:43:18 AM
Well documents that you saved to your desktop I can't comment on as I don't know why they they would be effected/garbled by avast, but if a file is corrupted it is very hard to do anything about them.

To do anything you would have to know what the initial file type was to have any chance of finding a tool that might be able to even recover some data. I think as you surmise they are effectively gone, unless you had a backup strategy in place to keep copies.

It's related to your TMP-directory being on a different drive than your Avast!-installation :(
Thanks . it's right : AIS on C and TEMP on D

Fixed on 7.0.1456 , I can restore my very old backup

And , no memory problem anymore after 12h test

@SirMatthew

i ran into this lately and this microsoft fixit tool fixed it for me

http://support.microsoft.com/kb/813711

Changes to the size, view, icon or position of a folder are lost
 
The changes to the size, view, icon or position of a folder are lost on a computer that is running Windows XP, Windows Vista, or Windows 7.

For example, you may experience one or more of the following issues:
•Microsoft Windows does not remember the View settings for a folder when you reopen the folder.

Note The View settings include Thumbnails, Tiles, Icons, List, Details, and so on.
•Windows does not remember the size or the position of a folder window when you reopen the folder.
•An incorrect thumbnail image is displayed for a folder.
•The thumbnail image does not appear for a folder.

maby worth a shot
