It may be in jboss server.log. Yes I checked the server log file but I am not seeing any outof memory error. Usually when JBOSS server is short on memory one would see a memory warning message later followed by java.lang.OutOfMemoryError. I am neither seeing the memory warning or outofMemoryError. As i said before from the JProfiler graph the max heap memory (-xmx) is never reached. Very Strange. Is this a JBoss defect ?
