Hi Lister's -
We are currently on 8.1.02 (working on upgrading to 9.1.4). It seems like our
Java plugins are being used more and more, with thinks like webservices, RKM,
AI, etc., and we have been seeing an increasing numbers of memory errors in the
arjavaplugin.log. Error such as:
2018-04-25 07:10:04,137 ERROR [pool-3-thread-2]
com.bmc.arsys.pluginsvr.plugins.a (?:?) - getListEntryWithFields() FAILs in

We are currently on Java 1.7.0_45, and what we have for memory sizes in the
armonitor.cfg are:
Java Plugin
-Xmx
-XX:PermSize
-XX:MaxPermSize
D:\Program Files\BMC Software\ARSystem\pluginsvr
2048m
128m
128m
D:\Program Files\BMC Software\ARSystem\pluginsvr\fts\primary
1024m
D:\Program Files\BMC Software\ARSystem\pluginsvr\fts\secondary
1024m
D:\Program Files\BMC Software\ARSystem\diserver\data-integration
1024m
D:\Program Files\BMC Software\ARSystem\assignmentengine\bin
256m
D:\Program Files\BMC Software\AtriumCore\cmdb\plugins\ne
512m
D:\Program Files\BMC Software\AtriumCore\cmdb\plugins\shared
512m
Are these errors indicative of not giving enough memory (fixing by increasing
the -Xmx?)
Or do I need to set more options, such as -XX:+UseConcMarkSweepGC and/or
-XX:+UseParNewGC in armonitor.cfg, such as, for the primary pluginsvr:
"D:\Program Files\Java\jre7\bin\java" -Xmx2048m -XX:PermSize=128m
-XX:MaxPermSize=128m XX:+UseConcMarkSweepGC -XX:+UseParNewGC
Any suggestions would be welcome!
Thanks,
