IIS6 w3wp.exe crashes (rtlfreeheap)

To all of my online friends.

I have a problem with my Windows Server 2003 SP 1 servers. I run IIS6
on the servers, and the w3wp.exe processes keep crashing.

I ran IISState and extracted the following log:


***********************

It seems as if there is a problem with the MSVBVM50 (Microsoft Visual
Basic Virtual Machine v5.0).

I've tried isolating the problem using Application Pools, and have
traced crashed both in old style asp application and new asp.net
application based on .net framework 1.1.

Any help appreciated.

PS! Please do not post answers like "Contact MS support" and "Reinstall
everything".

This is a crash that occurs during shutdown of the process - so nothing was
actually running at the time.

Basically VB was working through some cleanup and crashed b/c one of the
structures had become corrupt. This should not affect normal runtime.

You may be able to isolate the issue with PageHeap and a more invasive
debugging session using WinDBG.
