Hi Experts,


I am doing PoC including CAI for Japanese insurance company.

They are using JBOSS EAP 6 and GuideWire PolicyCenter(GWPC) application is running on it.

JBOSS memory settings are -Xmx2048m -XX:MaxPermSize=512MB because GWPC requires there sizes as a minimum requirement.

I installed CAI agent on JBOSS and try to start up JBOSS but did not start up properly.

I checked devtest_agent_XXXX.log and I found an "Out of Memory Error" on it. (See below)

The cause is, obviously, memory is not enough so I should ask to customer to increase memory settings much customer should increase? Do we have references or guides about it? This is my question.
