BUG #: 355430 (SHILOH_BUGS)



SYMPTOMS
When the transaction isolation level is set to READ COMMITTED, a SELECT statement that relies on prefetch and that causes a lock escalation may incorrectly hold a shared table lock on an underlying table until the end of the transaction. In this case, for a query running under the default READ COMMITTED isolation level, the expected behavior is for the shared locks to be held until the end of the statement, not the end of the transaction.
