koha-plack --stop doesn't ensure that Plack was really stopped before
returning. 

So in case that koha-plack --stop was quickly follows by koha-plack --start
(e.g. logrotate), it could leave Plack in stop state. This is due to koha-plack
--start think that Plack was already started, while it actually is being
stopped.

For me I think this is the cause why I got random Plack stop when logrotate is
run. 

It should be similar to the case of Zebra in Bug #16885, and the solution might
be the same: adding "--retry=TERM/30/KILL/5;" to start-stop-daemon command.

I just try that on our server and will see if the problem goes away.
