For 7 real computers, RabbitMQ is actually a better choice. You get centralized management and the most battle-tested driver of all. ZeroMQ is meant to remove the bottleneck and SPOF of a RabbitMQ cluster from much larger systems by making the data path for messaging directly peer-to-peer, but it still needs a central matchmaker database. So at that scale, you're not really winning much by using it. I can't really speak to the answers for your problems that you've seen, but in general I'd expect Liberty and Mitaka on RabbitMQ to handle your cluster size without breaking a sweat. Have you reported the errors as bugs in oslo.messaging?
