Speaking from experience :-) you will probably find this is from a
third party library or from unhanded exceptions in your code. If
you are using QuickTime for Java, that would be a prime suspect. The
other place this happens is in sleep() and terminate() of sessions.
If exceptions escape those, the session never dies and its memory is
never released. Does session count grow over the week? You can
monitor this by logging in Session:
NSLog.out.appendln("Current active sessions: " + application
().activeSessionsCount());
It is also useful to log out the session ID in the constructor and in
terminate() so that you can track down which does not terminate.
Finally, get a thread dump of the JVm after it has been running for
several days and see if there are stuck threads.
