Subj:   Re: Teradata Error 2971
 
From:   Ballinger, Carrie

There's a lock table on each AMP. That error means some activity has caused the number of lock entires to exceed the size of this table. An extensive number of rowhash locks being set and not released, for example, could fill it up. This could happen if single-row inserts were being done by a session that is in ANSI mode (no commit is automatically issued after each insert...you have to wait for a commit for the lock entries to be freed).

I'd try to look more closely at any application that might be setting rowhash locks: Try running the session in BTET mode, if its not already. Another alternative is to lock the table for write before the row-level inserts are performed, substituting one lock per AMP for many.

Thanks, --Carrie
