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.



CAUSE
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.
