Configuring Shutdown and Startup Time Limits
Applies To: Windows Server 2003, Windows Server 2003 with SP1
For a worker process that has a requested recycle, you can set the maximum time that the worker process continues to process requests before it shuts down. When you set the shutdown time limit (the default is 90 seconds), consider that a worker process shuts down gracefully when the configured shutdown time is long enough to allow it to finish processing its queued requests. Be sure you tune the shutdown time period to fit the load characteristics of the applications that are being processed. If the worker process cannot shut down within the configured time limit, a termination event appears in the event log even when the application shuts down gracefully.
You can also configure a startup time limit (the default is 90 seconds), which specifies how long the WWW service waits for a worker process to start before identifying the worker process as unhealthy and in need of being shut down.
