Bug #: 474645 (SQL Server 8.0)
Microsoft distributes SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
This article describes the following about this hotfix release:
When you run the DBCC INDEXDEFRAG statement, null mode page locks may accumulate on defragmented pages. These page locks may consume server resources. Then, the transactions that accumulate the locks try to escalate the page locks to table locks. The transactions escalate the page locks to try to reduce server resource usage. Because the DBCC INDEXDEFRAG statement takes an exclusive page lock and also causes the lock escalation to occur, you may experience concurrency issues.
Note You can use the sp_lock stored procedure to verify the mode of a lock.

To work around this problem, turn on trace flag 1211 on the connection that runs the DBCC INDEXDEFRAG stored procedure. Trace flag 1211 prevents the transactions that accumulate the locks from escalating the page locks to table locks. The null mode locks may still accumulate. If the null mode locks accumulate, you may receive an error message that is similar to the following:
Note We only recommend this workaround as a short-term solution. You should only turn on trace flag 1211 for the duration of the DBCC INDEXDEFRAG stored procedure. If you leave the trace flag on continuously, or if you use this trace flag as a startup parameter, you may experience additional issues from the side effects that are associated with this trace flag. We recommend that you only enable this trace flag for the duration of the DBCC INDEXDEFRAG stored procedure to avoid these issues.
Error : 1204, Severity: 19, State: 3 SQL Server has run out of LOCKS. Re-run your command when there are fewer active users, or ask your System Administrator to reconfigure SQL Server with more LOCKS
