AMQ 4.1.0 comes with Java Service Wrapper in the standard binary package. It would restart the broker for you. Until you figure out why it's stopping, that may be your best bet. That's definitely a somewhat organized shutdown. It's not just a JVM crash, which wouldn't log anything. (The most stable VM I've run AMQ in was Sun 1.5.0_09, so you may want to try that just in case.) Turn logging up and see where the shutdown init is coming from?
