Comment 4 for bug 1557337

Some extracts of discussion(only for reference):

"seems like there could be some improvements in cleaning up the output. so for that, sure, it could be worth fixing
eg the traceback output could be captured and turned into something cleaner and more helpful
I'd suggest starting with the traceback and treating that as one change by itself
and not worry with the pid or pidfile not finding an existing running process"

*Please dont consider this discussion extracts as final thoughts, this came out of some informal discussion so need to confirm further before fixing things on developer end*.
