CAUSE
When a COM+ library or server application is started, the application must register itself with the COM+ system application. This occurs when the first COM+ component is activated.
However, a problem can occur if the same single-threaded
apartment (STA) client thread activates two COM+ components in a COM+ library application. When the first component contacts the COM+ system application in an outgoing call to register itself with the COM+ system application, the call enters the STA modal loop. Because the same thread can handle a second activation request, the second component tries to contact the COM+ system application even though the first call has not yet returned. This problem occurs because the lock in the system application cannot serialize the two activation calls from the same thread.
For example, this scenario can occur when a COM EXE server that contains STA objects activates COM+ library components on the host STA.
