SYMPTOMS

When multiple users try to run extended stored procedures on an instance of SQL Server 2000 at the same time in a multi-user environment, the users may notice that the extended stored procedures take a long time to run. Additionally, when you run an application that uses multiple extended stored procedures extensively, the scalability of your instance of SQL Server 2000 may be affected. However, other users of the instance of SQL Server who are not running the extended stored procedures are not affected by this problem.

CAUSE

Every time that you run an extended stored procedure, the extended stored procedure acquires an exclusive latch multiple times to make sure that data integrity is maintained. When multiple users try to acquire the exclusive latches at the same time, latch contention occurs.

RESOLUTION
