The problem is that, when using --pidfile option, start-stop-daemon only sends the TERM signal to the parent process then returns. This happens fast enough for the do_start to be executed before the children processes have time to terminate. This causes the port used by stud to be busy when do_start executes in the 'restart' sequence so stud do not get restarted correctly. Using - --pidfile also make the --retry option to be active only on the parent process and not on the children. It is easy to confirm the statement by adding a lsof -i @127.0.0.1:8445 in the do_start function, just before start-stop-daemon gets executed. The stud children are still present. Removing --pidfile in do_stop's start-stop-daemon forces it to ack on the parent process and all the children process and makes --retry wait for termination of all of them. So in short, when using --pidfile, it only acts on the parent process and do not wait for the children to terminate.
