BUG #: 352735 (SHILOH_BUGS)
In a SQL Server 2000 Profiler trace, the EventSubClass column in the Lock:DeadlockChain event may show incorrect information.
To resolve this problem, obtain the latest service pack for Microosoft SQL Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

To determine the lock mode from a SQL Server 2000 Profiler trace, use the Mode column instead of the EventSubClass column. The values in the Mode column are integers; for a list of the possible integer values and the corresponding lock modes, see the documentation for the syslockinfo.req_mode column in the SQL Server Books Online topic "syslockinfo".
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 1.
The EventSubClass column in a Lock:DeadlockChain event is supposed to show the deadlock resource type. Before SQL Server 2000 Service Pack 1 (SP1), what appears in this column is a lock mode that is not related to the actual lock mode. For example, you may see "Schema Stability" when the actual lock mode is "Key". After SP1, the EventSubClass column correctly identifies the type of resource involved in the deadlock ("Lock", "Exchange", "Thread", or "Page Supplier").
