Exchange crashes after 4.8.1049 program update

[igor]

I did send Vlk a dump created just 5 seconds after the event occurred. Since the dump is half a gigabyte in size, and the Avast "Incoming" directory is write-only, I don't know yet whether my upload was successful.

Hello,

I don't know if you've communicated with Vlk by e-mail, but the upload on the FTP is only 2 megabytes in size - i.e. it's not complete.
Could you possibly try to upload again? (or, if you have a webspace of your own, put it there for download, probably in a form of a password-protected archive?)
Thanks.

I am currently uploading the file to a different server. I will let Vlk know when the upload is complete and how to retrieve the file.

I have e-mailed Vlk with instructions for retrieving the file from my server.

We're experiencing the same, more details:

1) emails are being sent out just fine.
2) incoming emails are sitting on the pending queue and not being delivered to local mailboxes.
3) event log is showing IMF being restarted, which i suspect is due to a restart of the smtp service more than anything.
4) this has happened since avast auto-updated on the windows 2003 sbs on sunday. Monday morning, start of business, was a firefighting session of trying to get ever growing queues to deliver.
5) all this was solved by disabling the local exchange and smtp scanners in avast. queue sizes dropped to nothing almost straight away.

The current result is that we are getting email delivered locally, but not virus scanned however. I've not seen requirement to uninstall avast. Just disabling the exchange and smtp scanner seems to fix it (after the smtp service is restarted).

Note however, that on reboot of the server, avast will be restarted again and delivery will fail once more.

Same problem here...

SBS2003 UK SP2.

Quick solution when no mail is deliverd anymore.

disable avast
start=>run=>issreset
then restart the mailstore
then from the Exchange systemmanager go to => servers => {servername} => queues
Right klik Messages pending submission and choose freeze.. Then wait 5 seconds and then klik it again and choose force connection.

Now the messages will be deliverd again......

Quick solution when no mail is deliverd anymore.

I find that the following two-step procedure is sufficient to restore delivery:

1. Restart the Microsoft Exchange Information Store service.
2. Force a connection with the Pending queue.

The Avast Exchange provider restarts immediately on its own after Step 1.

sometimes an ISSRESET is necessary

Guys, just a small status update.

We're still investigating the issue. Hopefully, there will be a fix in the upcoming couple of days.

Thanks

BTW one thing to try:

please go to avast settings, "Update (Basic)" page, click Details, and uncheck the "Enable" box in the "Push iAVS" section. Confirm with OK, and monitor if it makes any difference.

 Try this

and disable transport level in Avast task->Resident protection ->Exchange2000/2003 Scanning settings.

...maybe

I'm going to try it.. I will report the results in about 4 hours...

Okay.  I've unchecked the iAVS box.  We'll see if it works.  If not I'll try the hotfix noted in the MS link above.

this trick didn't work..

[Vlk]

OK, one more thing to try:

1. disable the MS SMTP 2000/2003 provider in avast ("Terminate" it); keep the Exchange 2000/2003 provider enabled
2. use iisreset to restart the inetinfo.exe process (which hosts the SMTP service).
