That is correct. The processes that are performing the i/o on the disk are separate jvms. It is not the same as the components using ActiveMQ. They high i/o usage are somehow causing ActiveMQ to stop. I've run many tests, with and without them running, ActiveMQ halts w/o any warnings/errors & it never recovers.
