We experienced the exact same issue with rabbitmq crashing with a two node
cluster. But what we found out is that it wasn't the management interface at
all. From our testing it seemed to be that one server was a disk node while
the other was a ram node. After changing the second server to a disk node
all seems to work correctly.

Obviously, the cluster should functioning whether the second node is ram or
disk based. We are going to setup another cluster on EC2 and see if we can
reproduce the results.
