App Pool Hang

Prev: could not create an instance of the IISScriptHelper object
Next: w3wp.exe exception

We have recently upgraded our website to .Net 2.0. Since the upgrade the
servers running our site have been hanging up and not responding to client
requests. We have done a number of dumps while the worker process is hung
but can't see exactly what the problem is. We can see some long running file
uploads but the vendor says its not their problem. If anyone can see
something in the attached debug diag log that could prove what the problem is
I would appreciate the help.

Damien,

Already gave a clue on another thread on using SOS to diagnose those
issues.
Please see:
http://groups.google.com/group/microsoft.public.inetserver.iis/browse_thread/thread/43db9307c23d5500/c9a9f17071adfed2#c9a9f17071adfed2

Good post on that tool but the dump looks almost the same as the debugdiag
tool's report. Any thoughts on what I should be looking for?

1) You need symbols - if you have a dump file, WinDBG can do this for you.
Without them, you won't get clean thread stacks (incorrect functions,etc.)
making analysis difficult
2) Most likely the issue is either a deadlock (in which case you actually
are experiencing a hang) or severe serialization (which makes things go so
slow, that they appear hung). I would say you are probably hitting a
serialization issue. Where & How I cannot say w/out clean thread stacks.
3) You need good symbols for SOS to work (which will get you the managed
stacks).
