Release : 11.4

Component : CA Workload Automation System Agent


Some Linux distro running older kernel have an issue with JRE and stack size.  This causes the JRE to throw a core dump.


Add the following parameter to the agentparm.txt




Note: If oscomponent.jvm.x.options parameter is currently present in the agentparm.txt, then append the -Xss2m  to the existing line with " ; "  as a separator.  Do not add a second line for oscomponent.jvm.x.options.  




Additional Information
