Files attached. The service is started like -
/opt/jboss/keycloak/bin/standalone.sh -c standalone-ha.xml -b=test-server-110 -bmanagement=test-server-110 -u 230.0.0.4 -Djboss.node.name=test-server-110
> Also, any chance you can try it out with master? I've been testing with that as we're about to do 1.4 release soon
Glad to give back to the community. Will build and deploy the master on my nodes. Will send findings tomorrow.
Regarding a scenario I described earlier -
Case 2
1. Start with 1 Node down. We bring it back up. We wait for some time so that Infinispan can sync.
2. Bring down other node.
3. Try to get user info using existing token.
Is this a valid use-case?

Also, any chance you can try it out with master? I've been testing with that as we're about to do 1.4 release soon
