On a server that has many processes running, the processModel/memoryLimit setting does not work.

This can lead to problems such as the following:
  • The Aspnet_wp.exe process does not recycle when the memory limit is reached.
  • The cache does not clear when the Aspnet_wp.exe process approaches the memory limit.
