A worker process took too long to shutdown.
A process serving application pool ''%1'' exceeded time limits during shut down. The process id was ''%2''.
This is usually caused by requests that are still in flight in the worker process that have not completed when the timeout expired.
Verify that all the requests that were in flight (look at the HTTPERR log to determine this) are valid requests. Consider increasing the ShutdownTimeLimit for the app pool if it is too short, but be wary of increasing it too much. Generally the application pool shuts down for good reason, and delaying that shutdown due to increased ShutdownTimeLimit is not advised.
