Hi All,

How are you? I am a bit confused about the errors reported by artemis slave
instance (running in clustered mode using jgroups). I might be missing
something here so please bear with me.

Deployment details: I am running 2 pods of artemis in master/slave
configuration in k8s. It supports NFS v4. I am using jgroups configuration
(same file which is supplied in examples of artemis) and I can see that
correct pod names and IPs are updated in share directory

-------- output from jgroups file ----------------
root@jms-01-deployment-6d7dcb8ccd-2t9g2:/opt# cat
/usr/share/artemis-jgroups/active_broadcast_channel/ab62408d-6a7a-4894-9923-2649d8bf3b28.jms-01-deployment-6d7dcb8ccd-2t9g2-29095.list

jms-01-deployment-6d7dcb8ccd-2t9g2-29095
ab62408d-6a7a-4894-9923-2649d8bf3b28 192.168.48.154:7800 T

--------------------------------------------------------

POD "jms-01-deployment-6d7dcb8ccd-2t9g2" is the master and another is
slave. Correct POD ips are listed there. But in log/artemis.log file of
slave pod, I see these logs

-------------------------------
2023-03-15 11:29:51,519 ERROR [org.apache.activemq.artemis.core.client]
AMQ214016: Failed to create netty connection

-----------------------------------

jgroups is correctly creating and updating files. IPs of master/slave pods
are visible from each other. I have tested them using command

"./artemis check node".
Right now I have created deployment objects. Is it necessary to create
stateful sets?

Am I missing something here? Let me know if you need more information on
this.
