The memory usage of the DFS Replication service keeps increasing on a PDC emulator or on a writable domain controller that is running Windows Server 2008 during the SYSVOL share replication process


View products that this article applies to.

Symptoms

Consider the following scenario:
  • On a computer that is running Windows Server 2008, you install the Distributed File System (DFS) Replication service.
  • You configure this computer to be a primary domain controller (PDC) emulator or a writable domain controller.
  • The DFS Replication is used to perform Domain System Volume (SYSVOL share) replication.
In this scenario, the memory usage of the DFS Replication service keeps increasing. If you monitor the DFS Replication service by using Performance Monitor utility (Perfmon.exe), you find that the Private Bytes counter keeps increasing.

Note This issue usually occurs on the Windows Server 2008-based PDC emulators or on the writable domain controllers in a domain that has many read-only domain controllers.

Cause

This problem occurs because the DFS Replication service does not free up some allocated memory during the SYSVOL share replication process.
