I suggest (no that those packages are not officialy from debian and not have the debian certification)
usage or "killall" if a non spected result are returned from stop service command, or at leas revise the pid file if still exist

NOTE: the server process must be killed due if thi are not killed database purge cound not performend if postgresql or sqlite are configured.
NOTE2: same for proxy cases...
