Make the logging connection cleanly shut down when an EOF is received from the GRPC connection. EOF indicates that the connection was shutdown by the remote end, so we should similarly shut down on our end. This is valuable in loop back mode where we see more of the worker side of logging. Also, make the "emergency" local log to STDERR more legible vs simply printing the proto struct. ------------------------ Thank you for your contribution!
