I wish I could in a timely manner...Guess I could try JProbe on trial license. I'm just trying to analyze why our multi-treaded app appears to grab heap from the system, it may run three days and the RES mem is stable, then the JVM thinks he needs more at undetermined times. For the long run, I would like to use this product though since we use JBoss and the Web interface is definitely a plus. Thanks!
