A memory leak occurs, and client requests may take a long time, when you run an application that is based on COM+ and that is registered as single-threaded

Consider the following scenario:

  • You run an application that is based on Microsoft Component Services (COM+) on a computer that is running one of the following Windows operating systems:
    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
  • The application relies on some COM+ components that are registered as single-threaded.

Note: The threading-model property of the components is set to Single Thread Apartment (STA).

In this scenario, you may encounter the following two issues:

  • A memory leak occurs in the COM+ application. Therefore, the application stops responding.
  • Calls from clients to the COM+ components are placed in a waiting status. Therefore, client requests take a long time to execute.
There is a download that resolves this issue. See Hotfixes for details.
