Sorry, that last sentence sounds wrong, let me restate: When I run several of those Test.java programs I attached, ActiveMQ stops. W/o these running ActiveMQ is fine. So I don't know if it is a system resource issue, if so, what? Or it is a condition that only arises when the system is bogged dow

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 &
