SOLUTION

Change –Xms ( for start heap memory ) and -Xmx ( for maximum heap memory ) of the opmn.xml.

Changing the Xmx to 512 MB and Xms to 128 MB will help.

Increase Java Heap Size for the OC4J instance as per the available memory (RAM) & restart the instance.

1. Do it with AS Control -> OC4J Instance -> Administration Tab -> Server Properties -> Java  options.
2. Update -Xms -Xmx java options.
3. Once updated, stop and start the OC4J instance to pick up the changes.
