Stopped Hashing

My Miner will just stop mining but when I reboot the machine it will start again, is there a way to reboot a machine automatically if it stops Hashing.

I have look through the forums and got the following but it is not working

I am running cgminer 3.9.0

====
C=`pidof cgminer | wc -w`
if [ "$C" != "1" ]; then
   /etc/init.d/cgminer stop
   /etc/init.d/cgminer start
   exit 0;
fi

A=`cat /tmp/cm.log | sed "s/ //g"`
B=`cgminer-api | grep "^ \[Accepted\]" | sed "s/ //g"`
echo $B > /tmp/cm.log
if [ "$A" == "$B" ]; then
   /etc/init.d/cgminer stop
   /etc/init.d/cgminer start
   exit 0;
fi
====

All I am getting is what is below when i look to see why it has stopped

Code:

[Firmware Version] => 20131229
cgminer: 698d677
cgminer-openwrt-packages: aadd747+
