Hi Logos and others,

we have found a bug, related to this High CPU usage in afwServ (and potentionally also application crashes of the Firewall service). It was related to the code that was responsible for verifying signatures of the running process. This fix was already delivered to you with the latest VPS update (VPS 100531-0).

Thanks a lot for helping us finding this bug.

Since this problem may have been causing memory corruption problems inside afwServ.exe, it might also be responsible for crashes reported previously. I hope that this was the last bug there and that the crashes will not reappear - which would mean there is something more.

Those of you who helped us track the bug by enabled special heap with pageheap.exe tool - please consider disabling the special heap. With special heap enabled the process will certainly consume more memory than needed. You can disable special heap by the following command:
Code: [Select]
pageheap /disable afwserv.exe
