Abstract
CL_HACMP (Doc Number=6377): High Impact / Highly Pervasive APAR IJ15739 IJ15739 - PowerHA may have unexpected failover due to clstrmgr memory leak
In a PowerHA SystemMirror cluster, an unexpected halt of the primary node and RG failover may occur.
This happens when the clstrmgr daemon leaks memory and core dumps when heap memory is exhausted.
The problem can occur after a PowerHA cluster running the affected levels below has been running for a long time, and clstrmgr daemon's memory usage has grown very large.
