You experience slow system performance when you run a program that uses the WMI service on a Windows XP SP2-based computer or a Windows Server 2003 SP1-based computer (911262)


The information in this article applies to:

  • Microsoft Windows XP Service Pack 2, when used with:
    • Microsoft Windows XP Home Edition
    • Microsoft Windows XP Professional
  • Microsoft Windows Server 2003 SP1

SYMPTOMS

When you run a program that uses the Windows Management Instrumentation (WMI) service on a Microsoft Windows XP Service Pack 2 (SP2)-based computer or on a Microsoft Windows Server 2003 Service Pack 1(SP1)-based computer, you experience slow system performance. This problem gradually becomes worse as you continue to run the program.

CAUSE

This problem is caused by a memory leak that occurs when the memory that is used by a remote procedure call (RPC) cache is not freed. As the RPC cache grows larger, the program and Windows XP or Windows Server 2003 become increasingly unresponsive.
