worker processes being recycled prematurely?

Would anyone know why worker processes would get recycled prematurely?

For example, say you log into a site and you're supposed to stay logged in
for 20-30 minutes or as long as you're active, but in 5 minutes it sends you
back to the log in page.

Something is forcing the worker process to recycle... either AV software or
mem usage?

How would we be able to determine what's happening here?

We're using IIS 6 on a Windows 2003 Server.

Thanks!

more info -
this is an ASP.NET 2.0 application that uses forms authentication
if that helps at all

Check the event log. Is it actually recycling or is it crashing,
there's a big difference.

Re: worker processes being recycled prematurely?

Is there a way to tell in the event log whether the worker process is
recycling?

Re: worker processes being recycled prematurely?

IIS will log an event for unexpected worker process recycling. Crashes
would belong to unexpected recycling.

Planned worker process recycling, such as periodic recycling,
recycling based on memory used, etc, do not raise events by default.

You can use a tool like ADSUTIL.VBS change the "LogEventOnRecycle"
property on the Application Pool of interest to make it log planned
recycling to the event log as well. It is a bit flag, so you can
control exactly which planning recycling metric to log to event log.
This property is for debugging and not exposed in the IIS Manager UI.
