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?
Thanks,
Steve

One interesting thing is that although the memory allocated as
reported by the processes tab of Windows Task Manager goes up and up,
and the JVM eventually crashes with an OutOfMemory error, the total size
of heap + non-heap as reported by jconsole is constant and much lower
than the Windows-reported allocated memory. I've also tried Netbeans
profiler, which suggests that the variables in the heap that are
continually surviving garbage collection do not all originate from one
class.
Smells like native memory leak? Can jconsole/jmap/jhat monitor native mem?
I once spent some time on what finally was a GZipOutputStream native mem
usage/leak. Moving from Java 1.5 to 1.6 could expose such problem...
