Maintain a list of objects for each type

The Maintain a list of objects for each type flag collects and maintains a list of active objects by object type, for example, event, mutex, and semaphore.



Hexadecimal value


Symbolic Name



System-wide registry entry



To display the object list, use Open Handles (oh.exe), a tool included in the Windows 2000 Resource Kit, and now available for download from the Microsoft Windows 2000 Resource Kit Web site. Because Open Handles automatically sets the OTL flag, but does not clear it, use GFlags -otl to clear the flag.

Note   The linked lists created when you set this flag use eight bytes of overhead for each object. Remember to clear this flag when your analysis is complete.
