Remoting Kafka Agent classloading breaks in some cases:
1) Remoting class fetching is asynchronous operation in the Channel instance. If something fails, classloading for the class will not be retried until the channel is reset
2) Remoting Kafka Agent holds the connection Channel, so it will stay waiting for classloading forever, even if the master receives command and then fails to respond
3) One of the response failures I see in debug (Classloader fetch3 command was received, but the response didn't get sent back):

W.r.t the " Successful log", we are getting an active channel which even responds to channel pinger.
But... There is hanging in setChannel() which prevents ComputerLauncher from existing:

My proposal would be to somehow invalidate classloader upon receiving a connection request from the master side
