Deleting Computers Fails With Out Of Locks Errors

• Microsoft Systems Management Server versions 1.0, 1.1 and 1.2

SYMPTOMS

Deleting a large number of computers from the SMS Administrator fails with "out of locks" errors. No computers are deleted, and the following error is displayed in a popup:

   Couldn't delete all the items.

   Error attempting to delete the requested items. Items have been removed
   from the query result list but not necessarily from the database.
   Refresh the data to ensure the result is correct.

   >>Msg>> SQL Server has run out of LOCKS. Re-run your command when there
   are fewer active users, or ask your System Administrator reconfigure SQL
    Server with more LOCKS.
   >>Msg>> The rollback transaction request has no corresponding BEGIN
   TRANSACTION.

All the computers in the query window get locked during a delete. Each lock uses 32 bytes, which at 10,000 locks will use up 320,000 bytes, which are then unavailable for caching the database.

WORKAROUND

The workaround for this problem with SMS 1.1 is adding more locks in SQL Server. If there is a one-time delete of a large number of computers, locks can be increased for the delete and reduced later.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server version 1.0 and 1.1. This problem has been improved with Systems Management Server version 1.2.
