Fix available in fixpack: Fix not currently available in a Service Pack, see below for information on an Interim Fix.

APAR status
Closed as fixed if next.
Error description
***************************************************************
* USERS AFFECTED:
* Systems running rsct.core.rmc 3.1.5.0 through 3.1.5.8,
* as well as rsct.core.rmc 3.2.0.0 through 3.2.0.4.
* This includes AIX 6.1 TL9 and AIX 7.1 TL3, and VIOS 2.2.3.
* Other AIX levels can be affected if RSCT has been updated
* independently of AIX.
***************************************************************
* PROBLEM DESCRIPTION:
* Starting in rsct.core.rmc 3.1.5.0, a slow memory leak in
* IBM.ConfigRM under CAA can lead to a cluster service
* shutdown, which causes to a node failure in both PowerHA v7
* (halt) and VIOS SSP (system panic).
* The leak occurs as long as CAA is active, regardless of
* what PowerHA or SSP is doing, and only on the node
* operating as the ConfigRM Group leader.  The GL node
* can be identified in "lssrc -ls IBM.ConfigRM".
* A reboot is guaranteed to reset the situation.  Time to
* failure after a new boot is estimated to be between 4 and 8
* months, although no existing records of failures in the
* field still retained the time of the last reboot, so a
* precise deadline is not known.
***************************************************************
* RECOMMENDATION:
* The fix for RSCT 3.1.5 is available via RSCT APAR IV66606.
* An interim fix for RSCT 3.1.5 is available from either:
* ftp://aix.software.ibm.com/aix/ifixes/iv66606/
* https://aix.software.ibm.com/aix/ifixes/iv66606/
*
* The fix for RSCT 3.2.0 is available via RSCT APAR IV69760.
* The fix for RSCT 3.2.0 will also ship with:
* AIX 6.1 TL9 SP5, AIX 7.1 TL3 SP5, and VIOS 2.2.3.5.
* An interim fix for RSCT 3.2.0 is available from either:
* ftp://aix.software.ibm.com/aix/ifixes/iv69760/
