Abend in PORTAL.NLM|SHealthMonitorProcess

There is a condition that exists where running any memory-monitoring utility on the server could cause an abend (i.e. SEG, NRM, iManager). The abends can differ somewhat, but the stack always shows us going through the call PORTAL.NLM|SHealthMonitorProcess.  Below is an example stackwalk:

0032A97C  SERVER.NLM|AnalyzeCache+60
81827EC8  0023CCFF  SERVER.NLM|GetLogicalSpaceInfo+3F
81827F0C  83E377A3 PORTAL.NLM|SHealthMonitorProcess+3C7
81827FE4  00222D48  SERVER.NLM|TcoNewSystemThreadEntryPoint+40

This abend is resolved in SERVER.EXE dated April 11 or later. This can be found in patch NW65OS5a.exe.
