GC Allocation Failure after switching to EAR from WAR

We are trying to switch to ear from war on our Pega 718/JBoss EAP6.3 environment. I made the required changes and started the server. The prpc_j2ee14_jboss61JBM.ear gets deployed fine and I'm able to log in to the designer studio. But in the logs I see continuous messages about GC Allocation failure as below.

This was not occuring when I had the prweb.war deployed.

I checked the heap utilization is too low and there is almost 15GB of heap free.

Any tuning to be done on this for ear file?
