> [This report is probably not describing a bug in ActiveMQ itself, but it shows up when using ActiveMQ and prevents it from functioning correctly, this is why I'm starting to report it at this level of the stack. Depending on feedback, it can be propagated further down the stack.]
> When running ActiveMQ on User-Mode-Linux, some of its parts (notably the transport connector registration with JMX) fails because some random id cannot be created due to lack of entropy in /dev/random. As opposed to /dev/urandom, /dev/random is known to not have a lot of entropy and to block any read access until the pool is filled up again. This is a known, documented and correct behaviour. For some reason, it seems that the Sun implementation's seed generator accesses this device in non-blocking mode and fails to read random numbers. Or maybe it is instrumented to do so from the code which uses it.
> Among other issues, it means that the listener on port 61616 is running while the Stomp listener on port 61613 won't be active. It would be nice to have someone with knowledge of the stack, including the use of Spring, to see whose fault causes this issue.
