SYMPTOMS

The COM+ Event System does not deliver timely or reliable statistics to subscribers of the IComTrackingInfoEvents event interface. This problem occurs when the following conditions are true:
  • You have COM+ applications that run on Windows Server 2003 Service Pack 1 (SP1) or Windows Server 2003 Service Pack 2 (SP2).
  • Your administrative program tracks the status and the performance of the running COM+ applications by subscribing to the IComTrackingInfoEvents interface.

CAUSE

This problem occurs because of performance issues with the COM+ Event System service. The COM+ Event System service is used to deliver statistical information through a COM+ Events-based subscription mechanism.
