A memory leak occurs in COM+ when you try to marshal user-defined types from one thread to another

You may experience a memory leak in Microsoft COM+ when you try to marshal user-defined types (UDTs) from one thread to another.

COM+ Interception code that is used for In-Process Marshaling caches a structure that contains type info. This cache is deleted periodically to keep the process space from growing too large. Sometimes this structure is not freed, and this behavior causes a memory leak inside COM+.

How to obtain the hotfix

This issue is fixed in the Windows 2000 Server COM+ 1.0 Hotfix Package 28. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
