Issue/Introduction

This is continuously being logged in the server.log on the Identity Manager VAPP server. I'm looking for recommendations and thoughts regarding this.

2022-12-21 20:26:35,681 WARN  [org.apache.activemq.artemis.core.client] (activemq-discovery-group-thread-dg-group1) 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 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=52e013c0-7fdd-11ed-84c5-005056b1718

Environment

Release : 14.3 / 14.4

VAPP 

or
Jboss 7.2 / Wildfly 15 deployments.

Cause

The error is due to stale server info in the application server cache

Resolution

In a VAPP based environment:

Issue the deleteIDMJMSqueue alias and restart the IM node with the stop_im and start_im alias to clear any cached data,

This should resolve the recurring "AMQ212034: There are more than one servers on the network broadcasting the same node id" messages from the logs.   


In a Non-VAPP based Jboss/Wildfly deployment:

Stop all IM nodes, then clear the standalone/tmp and standalone/data folders and start the node back up.
