Error description
You have a problem where you run out of global locks. This problem has a contributing factor of EYU0TSSD not releasing CACHELISTs when LMAS's are terminated, which means that the locks are not freed. ADDITIONAL KEYWORDS: INSUFSTG, EYU0XELK, EYU0XSRS, XELK_QUEUE_NOT_AVAILABLE PK47554

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: You notice that when MASes are * * removed from a CICSplex, all of the * * cache storage and global locks that * * were acquired during connect or join * * are not being released. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes must be recycled to pick * * up the new code. Note that the restarts * * do not need to be done at the same time. * **************************************************************** When a MAS is removed from a CICSplex or a CICSplex is discarded, module EYU0TSSD (TSSD - Topology System Deletion) executes in each CMAS in the plex to release acquired resources. This includes freeing the Resource Topology Descriptor Blocks (RTDBs) and the TOP resource map cache lists. The table of resource types mapped by Topology in module EYU0TSSD has not been updated with some resource types added in recent releases of CPSM. The RTDB storage and three cache lists for each of the missing resource types will not be released, resulting in orphaned storage in the TOP cache data space, and three global lock elements per resource.
Problem conclusion
Module EYU0TSSD was modified to add entries for six missing resource types to its RTDB Locator Table.

Comments
You notice that when MASes are removed from a CICSplex, all of the cache storage and global locks that were acquired during connect or join are not being released. When a MAS is removed from a CICSplex or a CICSplex is DiSCarded, module EYU0TSSD (TSSD - Topology System Deletion) executes in each CMAS in the plex to release acquired resources. This includes freeing the Resource Topology Descriptor Blocks (RTDBs) and the TOP resource map cache lists. The table of resource types mapped by Topology in module EYU0TSSD has not been updated with some resource types added in recent releases of CPSM. The RTDB storage and three cache lists for each of the missing resource types will not be released, resulting in orphaned storage in the TOP cache data space, and three global lock elements per resource.
