I've seen similar things with rabbitmq, in situation where the load & number of events to process is tiny but HA is some checkbox item to deliver without a serious QA process to measure if the setup is actually working effectively. Number of events in production we genuinely needed multiple rabbitmq nodes in the cluster to cope with failure of one or more nodes: 0 . Number of times when rabbitmq got too excited processing large messages that it delayed heart beating & subsequently decided that there was a network partition when there was in fact no such thing, leading the prod support team to step in and manually recover the cluster: > 0
