Error description
IBM Spectrum Protect Server memory usage increases daily. The "show alloc" command shows the allocated memory for Status Monitoring thread used to monitor replication work load continue to increase if the replication process is active. L2/Customer diagnostics: . Collect dynamic output of "show alloc", the data shows the allocated memory bytes for "StatusMonitorThread" from imrepl.c increases: For example: Jan: 29th: imrepl.c line xxxx: 18533340 entries for 23574408480 bytes (CopyNodeFsList) thread 35(StatusMonitorThread parent=1) Jan 30th imrepl.c line xxxx: 19451961 entries for 24742894392 bytes (CopyNodeFsList) thread 35(StatusMonitorThread parent=1) Jan 31st: imrepl.c line xxxx: 22466115 entries for 28576898280 bytes (CopyNodeFsList) thread 35(StatusMonitorThread parent=1) The problem can happen if both below conditions are true: 1: SHOW MONREPLINFO' shows : Sync pass 1 is running 2:" Q proc" shows replication is running. Note: The status monitor checks whether the server needs to perform the weekly comprehensive count of replication workload. While the thread that performs replication workload count is running the status monitor is incorrectly attempting to start another thread to do the replication workload count. This problem can happen if the thread, ReplCountSyncThread, and a node replication are running at the same time. . Versions/Platform Affected: IBM Spectrum Protect Server version 7.1.3 and above on all supported platforms Initial Impact: HIGH Additional Keywords: Memory leak imrepl.c StatusMonitor CopyNodeFsList MONREPLINFO ReplCountSyncThread tsm
Local fix
1: execute below undocumented command, to temporarily stop the status monitor from monitoring the replication workload. SETOPT ALLOWREPLWRKLOADMONITOR NO 2: recycle the instance as needed to release the already allocated memory.
