Description
Use case:
- starts 2 WildFly servers with the standalone-full-ha.xml configuration and additional ha-policy for the messaging-activemq server:
<replication-colocated request-backup="true">
<master check-for-live-server="true"/>
</replication-colocated>
The default configuration for the colocated's slave is (allow-failback=true, restart-backup=true).
Scenario:
1. Starts the 2 servers
2. Kill server #1
=> server #2 must activate its backup
3. Restart server #1
=> server #1 checks for a live server
=> server #2 must failback and restart the server #1's backup
=> server #1 is the live server
Currently at step (3), the activated server on #2 does not failback, the server #1 is started as live server and both uses the same nodeID.

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 continuously 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=cd605092-b933-11e5-ba21-cb5e13c1ea67
