Error description
ABENDS0C4 RC11 in CQM#LCSX This APAR addresses a race condition that can occur when multiple CQM or ASC (Audit SQL Collector) address spaces are started within seconds of each other, causing incorrect storage to be freed or reused and possible ABEND0C4-11 or ABENDSB78-18 abends in CQM/ASC to also occur. NOTE: The DB2 Query Monitor Collector started task shares code with the DB2 Audit Management Expert Collector and the InfoSphere Guardium S-TAP Collector started tasks. Customers running the Collector with either (or both) DB2 Query Monitor and DB2 Audit Management Expert or InfoSphere Guardium S-TAP may experience this problem.
Local fix
Stop the CQM/ASC collectors and the master address space, then start the CQM/ASC collectors one at a time (note: please do not start the second collector until thefirst one has fully initialized).
