9.5

Description (partial)

Symptom:
emsam_fault process under Prime Collaboration Assurance 9.5 grows in virtual memory allocation until an out of memory (OOM) event is encountered.

Observing the emsam_fault process via Linux top command on the affected system, it is possible to watch this process increment in VM allocation until the OOM condition is faced (e.g. 3 GB).  This results in the generation of a heap memory dump, similar to the following:

/opt/emms/emsam/log/Fault/Fault.stderr.log 
23-Jan-2014|10:34:19.484|ERROR|Fault.stderr|main|Caused by: java.lang.OutOfMemoryError: Java heap space

After restarting the system, issue re-occurs at a 20-30 minute interval on average.

Conditions:
Large server deployment with 1000's of active alarms
