I’ve got a really strange issue in one of my keycloak 10.0.0 clusters (k1,k2).
If I startup in the order k1, k2 everything works the cluster loads.
If I then restart k1. The infinspan times out and k2 is unusable too.
When this happens I got lots of these messages:
Uncaught server error: org.infinispan.util.concurrent.TimeoutException: ISPN000476: Timed out waiting for responses for request …
This also happens if I start k2 first and then try to start k1. so the cache should be almost empty.
There’s no firewall on the servers which run keycloak.
Netstat shows on both servers have a java task on 55200 listening.
Any ideas? Networking ?
