Summary

Internet Information Services (IIS) application pools can be periodically recycled to avoid unstable states that can lead to application crashes, hangs, or memory leaks. By default, application pool recycling is overlapped, which means that the worker process that is to be shut down is kept running until after a new worker process is started. After a new worker process starts, new requests are passed to it. The old worker process shuts down after it finishes processing its existing requests, or after a configured time-out, whichever comes first. This way of recycling ensures uninterrupted service to clients. However, if an application in the application pool cannot run more than one instance of itself at a time, overlapping rotation can be disabled.

Resolutions

Stop and start WA S

If WAS fails to recycle an application pool, the problem may self-correct. If the problem persists, a possible resolution is to stop and restart WAS. Stopping the WAS service will also stop the World Wide Web Publishing Service (W3SVC) and any other services that depend on WAS. Thus, you may also have to start these other services.

To stop and start WAS:

  • Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  • At the command prompt, type net stop was /y.

  • At the command prompt, type net start was.

  • To restart W3SVC, from the command prompt, type net start w3svc. Also, start any other services that were stopped when WAS was shut down.
