FIX: The Svchost.exe process leaks memory when you use CLB and if servers are under a heavy load (287512)


The information in this article applies to:

  • Microsoft Application Center 2000
  • Microsoft Application Center 2000 SP1
  • Microsoft Application Center 2000 SP2
This article was previously published under Q287512

SYMPTOMS

If you are running Microsoft Application Center 2000 Component Load Balancing (CLB), and if the servers are under a heavy load, a memory leak may occur in the Svchost.exe process that hosts the Windows Remote Procedure Call (RPC) service (Rpcss.dll).

Svchost.exe is a generic host process name for services that are run from dynamic-link libraries (DLLs).

CAUSE

This problem occurs because CLB is not freeing security credentials when the AcquireCredentialsForClient function does not work on some code paths.
