I have noticed a very strange behavior in my DNN 4.5.5 portal. Occasionaly, when the application is restarted, my error log will start filling up with errors. About 25 per second. Host and General exceptino errors. Eventually the portal gets overloaded and the menu dissapears. Or I'll get an "index out of range" error.

I can set the universe right again by recycling the application pool. My IIS is set up to recycle at 2 hour intervals and after 35000 requests and at 6:00,12:00, 18:00. Memory recycling is set at 750 for virtual memory and 256 for used memory. It's a fairly high traffic intranet site and the webserver is newer with 2 gigs of ram.
Ideas? I'm not much of a IIS expert so I'm not sure if it's setup correctly, or if there is an issue in 4.5.5. This did not happen in the previous version I was on (4.4.1) i appreciate any insight.
Thanks
