[rabbitmq-discuss] Instable HA cluster

[James Lewis]

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 
back up...?

Any help appreciated,
James
