Server stops after switching from 'local' DC to 'remote' DC

    Details

      Description

      Install WildFly on two different machines, add an 'admin' user and start the host-master.xml configurations on each node, like:

      machineA: (10.10.10.1)

      $JBOSS_HOME/bin/add-user.sh -u admin -p admin
      $JBOSS_HOME/bin/domain.sh --host-config.xml -Djboss.bind.address.management=10.10.10.1
      

      machineB: 10.10.10.2

      $JBOSS_HOME/bin/add-user.sh -u admin -p admin
      $JBOSS_HOME/bin/domain.sh --host-config.xml -Djboss.bind.address.management=10.10.10.2
      

      And then applying a simplified script like below to machineB:

      batch
      /host=master:write-attribute(name=name, value=slave)
      /host=master/core-service=discovery-options/static-discovery=primary:add(host=10.10.10.1, port=9990, protocol=remote+http)
      /host=master:write-remote-domain-controller(username=admin, security-realm="ManagementRealm")
      /host=master/core-service=management/security-realm=ManagementRealm/server-identity=secret:add(value="YWRtaW4=")
      run-batch
      
      /host=master:reload
      

      Executing this scripts results in a server log output like below and stopping of the 'DomainController':
