Hello all
I have a two node cluster of keycloak version 22.05.
The discovery protocol is jdbcping.
If I start node A first and node B after, node B cannot join the cluster.
If I start node B first and node A after, everything works fine.
The node B log reports errors like:
2024-01-10 08:48:43,462 WARN [org.jgroups.protocols.pbcast.GMS] (keycloak-cache-init) nodeB-46960: JOIN(nodeB-46960) sent to nodeA-26878 timed out (after 2000 ms), on try 0
After a while it gives up:
2024-01-10 08:49:02,002 WARN [org.jgroups.protocols.pbcast.GMS] (keycloak-cache-init) nodeB-46960: too many JOIN attempts (10): becoming singleton
It looks like a network issue but I cannot identify anything on this context.
Any hints where I could further investigate?
