w3svc error event 1011 application pool error.

Hi,

I have a windows 2k3 server withi IIS6.0. I have an asp.net application
running on .Net 2.0 .

Lately i have had sessions getting lost randomly. A user would store it in
one page and then it would be gone if he goes to the next page at times.

After dicsounting other reasons, i thought of taking a look at the IIS and
the possiblity that the worker process was getting reset.

I have tons of the following error in Systems Events Log.

Source: W3SVC
EventID: 1011

A process serving application pool 'xxx' suffered a fatal communication
error with the World Wide Web Publishing Service. The process id was '4236'.
The data field contains the error number.

Data
0000: 6d 00 07 80

After researching a bit on the web i installed Debug Diagnostic. I have got
dumps (in .dmp format) as well as log files. I looked at the log files as
well as opend the dumps in Debug Diagnostics. But i'm not sure how to
understand what it means.

Could anyone point me to a resource as to how to analyze log files / dump
files to locate what is causing the problem ? Or is anyone willing to take a
look at it ?

Thanks

Tarique, I don't see any response posted. Have you received anything back?
I'm having similar issues and would like to know what, if any recommendations
were.
