Cause

It is the designed architecture that the wrapper restart PC Service when it detected timeout.

In many case, it was caused by small memory setting. Please check the OutOfMemory message in wrapper log.  When you find that, increase memory allocation according with the following document.

Modify Maximum Memory Usage for Each Performance Center Service

If you don't find any symptoms related memory, enlarge the timeout value as following workaround.

 

 

Environment

OS: Red Hat Linux 6.x

Resolution

Please add the following line into '/opt/CA/PerformanceCenter/PC/conf/wrapper.conf' file and restart CA Performance Center process.　

wrapper.ping.timeout=120

 

Note:

Above setting extend twice of default 60 seconds. This parameter will reduce the frequency of process restarting, but the process slow down period sustaining long time.
