intermittent failures for web service

From: IIS Administrator (Administrator_at_discussions.microsoft.com)

I am running windows 2003 enterprise edition sp1 with IIS 6.0 and Oracle
client 9.2.0.1.0

When I run an application that connects to a web service located on this
machine I receive intermittent failures. CPU usage will spike to 100% and
the web service will not return control to the client program. I will then
have to kill w3wp.exe in task manager.

The following entry appeared in the System event log about 12 minutes before
the problem occurred. DRS is the application pool that the web service runs
in. However, the program accessed the web service successfully many times
after that event ID occurred.

Event ID 1011

A process serving application pool 'DRS' suffered a fatal communication
error with the World Wide Web Publishing Service. The process id was '3736'.
The data field contains the error number.
