increasing total unload class in JConsole increase

Question

i am using JConsole monitoring my application and i found the total unload class are increasing from time to time. and the heap size and used heap are increasing too. after sometime, my application crashed.

do anyone have a idea why is this happen? does this implies there is something like a memory leak ?

thank you

Have you profiled with [VisualVM](http://visualvm.java.net/)? — Marcelo, Feb 10 '12 at 08:52

I don't think it is memory leak. Are you seeing any increase in heap usage in jconsole? class unloading may happen in case where classloader is GCed (or) those classes designated as soft references. Here are couple of interesting discussion on why class unloading happens link1 and link2.
