I am running about 7 ASP.NET web application in Windows
2003 server. One particular web app experiences a strange
problem of crashing the application pool consistently. I
looked in to the event viewer and figured that the reason
for crashing is Event Id 1002 - 'Application
pool 'Crashing' is being automatically disabled due to a
series of failures in the process(es) serving that
application pool.'
There are also warnings logged for the crashing of worker
processes in this application pool and the event id for
them is either 1009 or 1011.
1009 - A process serving application pool 'Crashing'
terminated unexpectedly. The process id was '2968'. The
process exit code was '0x7f0ea553'.
1011 - A process serving application pool 'Crashing'
suffered a fatal communication error with the World Wide
Web Publishing Service. The process id was '2884'. The
data field contains the error number.
Note: The application pool has the settings to crash if
there are 5 worker process failure in 5 minutes.
Can some one tell me what could be the reason for the
worker process failure?
