> lost entire queues because a small network blip caused RabbitMQ to think there was a network partition, and when the other nodes became visible, RabbitMQ has no reliable way to restore its state to what it was I can offer a similar anecdote: we started seeing rabbitmq reporting alleged cluster partitions in production after enabling TLS between rabbitmq nodes, where manual recovery was needed each time. After a bit of investigation we noticed that cluster partition seemed to correlate with sending an unusually large message (think something dumb like 30 megs) through rabbitmq when TLS between rabbitmq nodes was enabled. What I believe was happening was Rabbitmq was so busy encrypting/decrypting large message that it delayed sending or receiving heartbeat & then the cluster falsely assumed there has been a network partition. Mitigated that issue by rewriting system to not send 30 meg messages- there was only one message producer that sent messages anywhere near that large, and after a bit of thought realised it was not necessary to send any message at all in that case (sending large message was to hack around some other old system performance problem that had gotten fixed properly a year back, but the hack that generated a huge message was still in place)
