Boris Godunov commented on ARTEMIS-1427:

Yes Justin, i did receive responses from MichaelAndrePearce. To no avail though, my cluster
still goes "split brain". And I  have deleted all my duplicate posts almost immediately after
posting them.

> I have 2 brokers, one is master and another one is slave. When i stop master, slave becomes
live and everything looks fine. But when i start master back up, the logs of both brokers
are flooded with the following warning messages:
> 13:54:24,106 WARN  [org.apache.activemq.artemis.core.client] AMQ212034: There are more
than one servers on the network broadcasting the same node id. You will see this message exactly
once (per node) if a node is restarted, in which case it can be safely ignored. But if it
is logged continuousl
> y it means you really do have more than one node on the same network active concurrently
with the same node id. This could occur if you have a backup node active at the same time
as its live node. nodeID=ef2c7a0d-9e24-11e7-8dd6-e83935127c4c
