SYMPTOMS

You may experience activity deadlocks in a Microsoft COM+ application. This problem occurs when a COM+ activity makes an Out-Of-Apartment (OOA) call. Typically, the activity deadlocks occur when a transaction is aborted and that transaction has COM+ components from multiple apartments or processes.

CAUSE

This problem occurs because a bug in the COM+ activity lock code lets a thread deadlock when the thread tries to re-enter an activity.

STATUS
