Hi, did you have any luck with this? I'm just setting up a rabbit cluster
for my team and I'm running into exactly the same problem. What worries me
is that the docs on clustering say that the network connection between
nodes *must* be reliable - I was hoping that a 3 node cluster would
continue running if the connection between 2 nodes dropped and then allow
the dropped node to join back into the cluster when the connection came
Any help appreciated,
