Bind() Error about crts HOT 1 CLOSED

Hi, ctr+z doesn't terminate a process, it puts it in the background. If you run ($ top) after ctr+z, you would still see crts_controller running. Since the process is still running, the socket is still bound and you cannot start a new process that binds to it. Logging out of your SSH session terminates all processes including those in the background, so when you log back in you're able to start crts_controller again. To terminate the process you want ctr+c.
