Hi Mat

If you are using Jconsol you could also try use Jvisualvm for a
slightly different way of seeing the memory where the java objects are
stored. It shows the committed memory not currently holding objects in
more detail.

Another way to look at Java memory is to enable logging and read the
log file or put the log file thru a viewer tool.

logging changes to apply on JVM args:
-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -
verbose:gc -Xloggc:cfjvmGC.log

log viewer tool:

Ditto update JVM to current 1.6.0_26 or _24 if you prefer being on
officially supported platform.

HTH, Carl.
