Yes Deepak. We had few outofmemory issues with our server. The jmsstore size is 2 gb mostly caused by error queues.
The server restart also have been very slow. Once we had to kill the server and after that it refused to startup. The
thread dump shows a fatal exception when reading from store. The jmx of the server is 2 gb. So it could be either because the force kill have caused a corruption of file store or the jms store size is too big.
We are planing for a test where we could load a jmsstore and see how the jstat results differ.
