I was able to reproduce this bug. Simply create a process,
put its pid in a file, and call start-stop-daemon:
sudo start-stop-daemon --stop --pidfile /tmp/pidfile --retry 5
The result is the error message:
start-stop-daemon: warning: failed to kill 2679: No such process
which is presumably generated on the second pass of the retry sequence.
The return value is 0.
