This also likely affects Tumbleweed, Leap 42.2 and SLE 12 SP2 because all of them share the same service file. For reference the upstream service file recommendation is this: https://github.com/rabbitmq/rabbitmq-server/blob/90a1e737dec654dacb284c8245c163d846070b34/docs/rabbitmq-server.service.example but we can't use it because our erlang-epmd epmd.socket/service always run on 127.0.0.1. The upstream file uses a epmd@ template to make epmd@ listen to all addresses. Previously, rabbitmq-server could only run on 127.0.0.1. The current situation is not ideal, but it currently allows you to run rabbitmq-server on whatever IP you want. So if rabbitmq-server needs fixing, it's best to fix epmd at the same time.
