I actually had to deal with a leak in non-heap native memory once. I am running on Linux so I just use good old "ps" to monitor native memory usage.

Thanks. If the extra memory allocated is native memory I don't think jconsole includes it in "non-heap" as it doesn't show this as increasing, and jmap/jhat just dump/analyse the heap. Do you know of an application that can report native memory usage?
