Configuring Recycling Settings for an Application Pool (IIS 7)

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

If you have a problematic application and you cannot easily correct the code that causes the problems, you can limit the extent of these problems by periodically recycling the worker process that services the application.

In addition to recycling an application pool on demand when problems occur, you can configure an application pool to recycle a worker process for the following reasons:

  • At a scheduled time

  • After an elapsed time

  • After reaching a number of requests

  • After reaching a virtual memory threshold

  • After reaching a used memory threshold

For information about the levels at which you can perform these procedures, and the modules, handlers, and permissions that are required to perform these procedures, see Application Pools Feature Requirements (IIS 7).
