SYMPTOMS
When you use COM interop cross-context interface marshaling in the Microsoft .NET Framework 1.1 Service Pack 1 (SP1), a deadlock may occur. The deadlock occurs between the thread that is holding the COM activity lock and the thread that is holding the IUnkEntry lock. This problem is more likely to occur when a COM object is shared among different COM activities.
