Event ID 1009 - Application pool terminating.

There is a similar question posted today, but the event ID is different

I see the following error anywhere from 2-3 times a day on Windows 2003
server.
Event ID- 1009, a process serving application pool 'Q' terminated
unexpectedly.
The process ID was 'xxxx' . The process code was 'xxx'

So far we have not noticed anything on the application side, but once in a
while W3WP.EXE starts using up all the CPU and the server comes to a halt.
This is not associated with the application pool terminating, but wondering
if it is conntributing it.

I have applied SP1 for Windows 2003, that did not make any difference.

Any help is apprciated.
