Ok, it's definitely not the network then ;)

Hmm, that's interesting. It suggests rabbit is very busy. Does this
happen before the nodedown messages start happening - if Rabbit is
sufficiently busy then it could be failing to schedule the net ticktimes
70 msgs/sec is very low - Rabbit running on a decades-old PC will be
able to manage that. Thus what led you to setting up the cluster in the
first place and what topology / use cases do you have?
