Probleme mit cron + init.d + sudo

Hallo zusammen,

derzeit versuche ich einem Script, welcher eine Serveranwendung starten, bei Crash neustarten und restarten soll, für meinen Bedarf an zu passen. Der script kommt nicht von mir, daher auch die Probleme mit der Anpassung (verstehe nicht viel von shellscripting).

Code:

#!/bin/bash

### BEGIN INIT INFO
# Provides:                a3server
# Required-Start:        $remote_fs $network
# Required-Stop:        $remote_fs $network

# Should-Stop:        mysql
# Default-Start:        2 3 4 5
# Default-Stop:        0 1 6
# Description:        ArmA 3 init.d Script by Flodding

a3_stop() {

    echo ""
        killall -9 -u $USERNAME

    echo ""

}


case "$1" in

    a3_start

    if [ -f ${PIDFILE} ]; then

exit 1

exit 0

Mein Problem welches ich habe, wenn ich einen Cronjob definiere, welcher alle 5 Minuten /etc/init.d./a3server start ausführt, passiert einfach garnix. Allerdings sollte der Script eigentlich so sicherstellen, dass der Server läuft. Weiterhin funktioniert Restart und Stop nicht richtig, sobald der Server gestoppt wird, schließt sich die gesamte Konsole.

Kann hier jemand helfen?

Vielen Dank!
