"The SIGHUP signal is sent to a process when its controlling terminal is closed" #4

If you run socketmaster -command my_command & and then close the shell, socket master will start a new child process

Maybe use USR2 instead?

nope. HUP is also used by unicorn. I started a Go process started via an ssh session, put it into the bg and then closed the ssh session, no HUP signal was received.

OK thanks for confirming this. I had seen HUP being used for soft reloads in the past so it seemed appropriate. On Jul 25, 2013 10:03 AM, "Sam Taylor" notifications@github.com wrote:
