DSNT804I   csect-name THERE ARE MODIFY LOCKS OWNED BY THIS DB2 THAT HAVE BEEN RETAINED

When DB2® disconnected from IRLM during DB2 shutdown, IRLM indicated that there were still outstanding modify locks. These locks were retained by IRLM. The retained locks continue to protect the resources on which they are held from requests from other DB2s in the data sharing group. That is, IRLM rejects any lock request from another DB2 that is incompatible with the retained state of the lock. The locks are retained until the terminating DB2 subsystem is restarted and the resources on which the locks are held are recovered.
