Good morning!

We have a website running DNN 6.2.2. on W2k8 R2/IIS7 that is giving us an error when closing connections.  In the event viewer, we receive this entry:

"A process serving application pool 'QV-APP-11862_QA_CorporateSite' exceeded time limits during shut down. The process id was '8368'."

When verifying in the database, we get this error description:

We've tried to set the cache folder as an exception to the antivirus real-time scan, we've verified the settings of the website and it is configured the same as our non-dotnetnuke sites, and they are not timing out when closing connections.

I've tried running the debug diagnostic tool from Microsoft, but did not pickup anything that seemed to time out.  The website works, but we'd like to have it not throw this error, and hopefully the solution is something other than "extend the timeout period."

Thank you for your assistance.
