Important
This feature of IIS 6.0 is available only when IIS is running in worker process isolation mode.

In worker process isolation mode, IIS can be configured to periodically restart worker processes, so that you can recycle faulty Web applications. This helps ensure that applications in those pools remain healthy and that system resources are recovered.

You can configure worker processes to restart based on elapsed time, number of requests served, scheduled times, and two types of memory usage.

This section includes the following information:
