SYMPTOMS
When you stop a SQL Server transaction after that transaction requests a lock, the SQL Server 2000 Analysis Services process may stop accepting connections and may appear to stop responding.

810185 SQL Server 2000 hotfix update for SQL Server 2000 Service Pack 3 and 3a



CAUSE
Because locks are frequently requested and released in Analysis Services, the server uses a pool of structures for lock request information. This approach streamlines lock request operations by reusing the lock request structures. The approach does not create and destroy the lock request structures on demand.

If a transaction is aborted when a lock request is waiting, the lock request structure may be returned to the pool without being removed correctly from the lock waiter list. Another transaction may request a lock on the same object and may use the same lock request structure. In this case, the Analysis Services process detects that a request exists on the lock waiter list. Then, the Analysis Services process tries to insert the request at the end of the list.

The current transaction has the same lock request structure as the transaction that is already on the lock waiter list. Therefore, the next pointer for the lock request structure on the waiter list points to itself. Any subsequent lock request on the object will enter an infinite loop when the Analysis Services process tries to insert the lock request in the lock waiter list.
