SYMPTOMS

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

This hotfix changes the behavior of the asynchronous finalization of ServicedComponent objects to avoid the symptoms that are described in the "Symptoms" section. The DisableAsyncFinalization registry entry can be used as a temporary workaround only for deadlocks. However, this workaround may worsen the other symptoms of slow performance and memory leaks.

The correct approach is the systematic use of the Dispose method by the client of the ServicedComponent objects on all instances of the ServicedComponent class. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
