Check your thread pool configuration! Automatic recovery to be triggered by remaining consumers. Does your thread pool allow you to create up to 500 threads? This question really doesn't have anything to do with ActiveMQ, so although you might get an answer here, I'd strongly suggest that you post it on the Spring mailing list and on StackOverflow (since lots of people who know Spring hang out there).
