FIX: An event may be logged when you manually start a COM+ application on a computer that is running Windows Server 2003 with Service Pack 2: "The average call duration has exceeded 10 minutes"

Support for Windows Server 2003 ended on July 14, 2015

Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

On a computer that is running Windows Server 2003 with Service Pack 2 (SP2), the following event may be logged when you manually start a Microsoft COM+ application that uses object pooling:

The average call duration has exceeded 10 minutes. If this is not the expected behavior, please see article 910904 in the Microsoft Knowledge Base at for details on how to use the COM+ AutoDump feature to automatically generate dump files and/or terminate the process if the problem occurs again.

For a COM+ application that does not use object pooling, this event is logged if the first call to the COM+ application is from a remote client. This event is not logged for the later calls to the COM+ application.
