This issue is really hard to reproduce. The problem is that one of the nodes goes into constant loop trying to join the cluster while other nodes are trying to forget it. There is no known solution for this, but workaround is to do following:
stop rabbitmq on all controller nodes:
crm resource stop master_p_rabbitmq-server
then on each controller node remove mnesia database for rabbitmq:
