The server is set to its default configuration to recycle the app pool every 1740 minutes. When this happens the following message is logged:
A worker process with process id of '1234' serving application pool 'XX' has
requested a recycle because the worker process reached its allowed
processing time limit.
Directly after logging this message, the web site is unresponsive. The only way to get it back online is by running iisreset
manually.
Does anyone know a fix for this behavior, other than turning the recycle feature off? Is it a known problem?
EDIT1:
The problem has been isolated to a specific patch release. I'll be researching the changes in the patch in the coming week, and update / answer this question with the solution or more detailed problem depending on what I'll find
