Recompiles iis6 32-bit asp.net 3.5 running on 64-bit Windows Server 2003

I'm running a 32-bit asp.net app on iis6 on windows server 2003 (64-bit) and am encountering the following problems:

1. App takes 15-20 seconds to spin up.
2. App works quickly for a bit.
3. Something happens - maybe a recompile? The app takes 15-20 seconds to spin up again.

Nothing odd in Event Viewer or IIS logs- page eventually gets served up with a 200. Security log shows NETWORK SERVICE calling IUSR "success."

Also running filezilla ser开发者_Python百科ver and Symantec Endpoint Protection.

Any ideas how to further trace this or what to check in my configuration?

The application isn't restarting- it seems to start fine and then take requests from one of my browsers. When I switch to another browser and start trying to access the site, it hangs for a couple of minutes.

I logged application-start in global.asax.cs and it starts fine - and quickly.

Have you checked that the application pool allows 32 bit application? In advanced box of application pool there are a setting to allow this.

Check this screendump, with the standard setting for 64 bit machine (false) enabled. http://tinyurl.com/3jcr9mw

Not the issue - it's been set properly to 32-bit mode. Unsolved
