> I've got into this situation on 2 agent hosts after I've upgraded ambari-server, reset database and restarted ambari-server few times. Probably there was a rare case when agent got connection exception during registration, and it was not catched. So agent registration failed, and I had to go to agent host and to start agent manually.
> The expected behavior for an agent is to ignore any server-side connection problems and stay alive.
