Event ID 783 is logged unexpectedly in the Application log when you manually start a Microsoft Component Services (COM+) application in Windows Vista or Windows Server 2008

You have a computer that is running Windows Vista or Windows Server 2008. When you manually start a Microsoft Component Services (COM+) application that uses object pooling on the computer, the following event is logged unexpectedly in the Application log:

Log Name: Application
Source: Microsoft-Windows-Complus
Date: <Date Time>
Event ID: 783
Task Category: Process Dump
Level: Information
Keywords: Classic
Description: 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 http://support.microsoft.com 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.
Server Application ID: {Application id}
Server Application Instance ID: {Application Instance id}
Server Application Name: Application name

Note If the COM+ application does not use object pooling, this event is logged only when the first call to the COM+ application is made from a remote client. This event is not logged for later calls to the COM+ application.

This issue occurs because the hang detection timer of the operating system is set to -1 when you manually start a COM+ application that uses object pooling. This indicates that the data for hang detection is not available. However, "-1" is incorrectly interpreted as a very high call time. Therefore, the event is logged unexpectedly in the Application log.
