For all of you who ran into issues with ActiveMQ 5.0.0 when running it in anger, I highly recommend you give the just released ActiveMQ 5.1.0 a try. This release focused focused on making the broker rock solid. It resolved several bugs which only reared their heads in high load situations. Memory leaks have been squashed and performance has even improved in several areas.

Even if you have not had seen any issues with your 5.0.0 installation, I’d highly recommend you upgrade to 5.1.0 to avoid running into some of the bugs that have been addressed in the release.
