An access violation may occur in the Microsoft Message Queuing 2.0 run time (Mqrt.dll) when the run time is loaded in a COM+ application on a Microsoft Windows 2000 Server-based computer. A message that is similar to the following is logged in the application event log:
Event Type: Error
This problem occurs because a thread can be assigned to multiple activities in COM+ applications. This behavior causes excessive Message Queuing API calls in a relatively short time. If the thread is reentered while previous activity is blocked, the Mqrt.dll run time stops responding.
