During a warm start, the DB2 ECCR processed the list of outstanding UOWs that the Logger has recorded as in progress from this ECCR. This list is used to notify the Logger when these UOWs terminate, so that the Logger can remove related records. Otherwise, the outstanding UOWs might affect ECCR restart. While processing the specified UOW, the ECCR determined that this UOW is a duplicate in the list.
Processing continues. The duplicate UOW is dropped, but the original entry will be processed.
