First, verify that the first instance really has been undeployed. Second, unless you insure that at least two full GCs happen after undeploying the first .war file, class unloading will not occur. Even then, it's a bit of guess whether or not the JVM will choose to unload classes in the absence of pressure on PermGen. Regardless, as others suggested, running some heap analysis tool will find out if you've got a leak built into your webapp, or if the JVM has simply decided not to bother with class unloading yet. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
