Wildfly -9.0.1.Final : Domain configuration - discarded messages issue

Hi,

When trying to set up a domain configuration as explained in https://docs.jboss.org/author/display/WFLY9/WildFly+9+Cluster+Howto, I got lot of discarded messages both in MASTER and SLAVE servers.

I believe this is the reason why the SLAVE instances are not reflected in the admin console of MASTER.

[Server:server-three] 11:35:23,981 WARNING [org.jgroups.protocols.UDP]

(OOB-18,ee,master:server-three) JGRP000010: packet from 10.81.169.177:45688 has different version (3.2.7) than ours (3.6.4); packet is discarded (received 11 ...)

[Server:server-three] 11:35:23,985 WARNING [org.jgroups.protocols.UDP]

(OOB-11,hq-cluster,master:server-three) JGRP000010: packet from 10.81.169.177:45688 has different version (3.2.7) than ours (3.6.4); packet is discarded (received 11 identical messages from 10.81.169.177:45688 in the last 66660 ms)

Is this a bug ? https://issues.jboss.org/browse/WFLY-4971 Do anyone faced the same kind of issue ?

Thanks,

Venky

You need to isolate your jgroups clusters. You appear to have an existing jgroups cluster (using an older version of jgroups) on your network that uses the same multicast address/port. Make sure each cluster uses a distinct multicast address/port.
