FIX: Shared page locks can be held until end of the transaction and can cause blocking or performance problems in SQL Server 2000 Service Pack 3 (SP3)

Bug #: 471578 (SQL Server 8.0)

SYMPTOMS

In Microsoft SQL Server 2000 Service Pack 3 (SP3), shared page locks can be held until the end of the transaction. This behavior may lead to blocking or performance problems.

Back to the top | Give Feedback

This problem occurs if the SELECT statement uses a parallel index scan or a seek operation during a transaction when the transaction isolation level is set to READ COMMITTED. COMMIT or ROLLBACK operations determine the length of time that the shared page locks are held.
