Hi, It´s difficult to provide a whole step guide, because it´s a domain controlled cluster with master and 3 slaves. It happens 4 out of 5 starts and as I see it only on the first slave. I wait for every slave boots and then start the next. The first slave produces the unregister message, but the master does not recognize this unregister in its logs. I use Keycloak 3.1.0 with postgres cluster over pgpool.
