      When the controller was last restarting, some swarm agents never re-appeared. Some hours after that I logged in to check on them, and found the last logged interaction was the HTML response about "Starting Jenkins"; a retry after that never happened:

      This is a large inconvenience - to recover I have to log into the workers or have a way to reboot them, after I notice they are AWOL at all.
