.NET Runtime 2.0 Error Reporting - mscorwks.dll failing

[Florian Doyon]

Hello,

I am having issues with a .net 2.0 service randomly crashing on an 8
way machine running a 32bit .net server 2k3.

The event log contains an entry indicating that there's a fault in
mscorwks.dll, no stack trace attached, no dump, no drWatson, nothing.

I just configured the system to take a crash dump, but the mean time
to failure being 32 hours, I'd like to know where to look for my crash
before it occurs again (joys of random production issues).

The app uses a 3rd party mixed-mode dll, and relies heavily on
multithreading and async I/O, so there are too many area where it may
crash.

I did notice on thing in the two eventlog entries I got, is that the
faulting addresses are always the same. I let the app ran for 2 hours
before taking a memory snapshot, but I couldn't find the offending
method.

Thanks a lot guys!
