> A unique writeId has to be assigned for the table in global locks because this will help in cleanup of records in COMPLETED_TXN_COMPONENTS table. Currently the writeId is NULL for this table. There was a situation which lead to large number of records in COMPLETED_TXN_COMPONENTS table because these records had writeId as NULL and this subsequently lead to OOM errors.
