IIS crashes and restarts without dropping a mini-dump

Question

I have a tough scenario I\'m trying to debug... On a web forms page, when I click submit, the web server hits some error and restarts the w3svc process.

I do not see any

Answer 1

To create a memory dump for a crashing application, you can use either DebugDiag or adplus. Either will monitor the process, and generate a dump file when the crash occurs. DebugDiag can also analyze dump files and generate an issue report (similar to the "!analyze -v" command in WinDbg.)

DebugDiag can be downloaded here.

You should find adplus installed with the Debugging Tools for Windows - which is the same installer that contains WinDbg.
