RabbitMQ is only amazing if your cluster is 100% available, you have no soft lockups, no high load, etc. Its cluster failure handling is absolute crap. In our stack it's the buggiest, most unreliable piece of software we are running, and it's falling over (losing cluster state, hanging, crashing, etc) on an almost daily basis. We used to run 8 nodes, and it was a nightmare recovering from partitions. Now we've reduced it to 2 per cluster, and it's still a nightmare.
