I only get this WARN during the failover so it shouldn't be a problem. I found a solution for my missed remote client failover: now the remaining node (which is notified of the cluster topology change) waits 10 seconds before posting the message on the LostNode topic. It looks like i was posting the message during the failover, and that that was why the client couldn't receive it.
