  <p>I've tried many thing to solve but only way at moment is the manual start:</p>
  
  <pre><code>start-stop-daemon   --quiet --start --exec /usr/sbin/fbguard --pidfile /var/run/firebird/3.0/firebird.pid -b -m -- -daemon -forever -pidfile /var/run/firebird/3.0/firebird.pid
  </code></pre>
  
  <p>And manual stop:</p>
  
  <pre><code>start-stop-daemon --stop --signal KILL --exec /usr/sbin/fbguard 
  start-stop-daemon --stop --signal KILL --exec /usr/sbin/firebird
  </code></pre>
  
  <p>Any ideas?</p>
