[keycloak-user] JGRP000010 Version Mismatch errors from running in HA mode

[Eugene Chow]

Hi guys,

I’m running a Keycloak cluster testbed and I keep getting this message even though only 1 instance of Keycloak is running in HA mode. The Keycloak instances are running in KVM containers on a single host machine.

> 04:08:36,494 WARNING [org.jgroups.protocols.UDP] (Incoming-4,ee,keycloak1) JGRP000010: packet from 192.168.122.1:1029 has different version (3.4.5) than ours (3.6.4); packet is discarded

It seems like Keycloak/Infinispan is sending malformed (ie. version mismatch) multicast packets that it would reject. Is there a way to fix this?


Thanks in advance!
