----------------------------------------
i tried to post to Active MQ user group, but my attempts failed. This the
problem that I tried to post:
I have to restart my 2 broker cluster on a daily basis due to the following
sequence of events:
-----------------------------------------------------------------------------------------------

-----------------------------------------------------------------------------------------------
I understand that at some point master (now live) loses slave and closes
connection to it.
Slave (backup now) in turn detects that master is not present and becomes live.
Now both brokers are live and never recover to normal until restart.
How can I avois this? Will appreciate any help.
Thank you.

> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.5.3
> Environment: Linux 2.6.18-419.el5 #1 SMP Wed Feb 22 22:40:57 EST 2017

> 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.
