Symptoms

You encounter a memory leak on a network file system (NFS) share server that is running Windows Server 2008.

Cause

This problem occurs when the lifetime of the delta queue elements is changed incorrectly to an arbitrary large value. This causes the cache entries to be retained for a long time.

Note The delta queue in NFS is used to track the cache entries that are no longer being used and that can be cleaned up based on their time-outs.
