Process Killer (Helpful for your server) So I was doing some research and I found this script to use for your server, I have tested it out and tweaked it on my own machine, so if you are interested contact me so I can start making the tweaks so it is optimized for the retrograde server.

Process Killer

#!/bin/bash
##Note: will kill the top-most process if the $CPU_LOAD is greater than the $CPU_THRESHOLD.
#################### FOR TEST PURPOSES ONLY STILL NEEDS TO BE TWEAKED!!!#################
echo
echo checking for run-away process ...
 
CPU_LOAD=$(uptime | cut -d"," -f4 | cut -d":" -f2 | cut -d" " -f2 | sed -e "s/\.//g")
CPU_THRESHOLD=75 # This needs to be customized for the server so it knows when to start killing programs.
PROCESS=$(ps aux r)
TOPPROCESS=$(ps -eo pid -eo pcpu -eo command | sort -k 2 -r | grep -v PID | head -n 1)
 
if [ $CPU_LOAD -gt $CPU_THRESHOLD ] ; then
  kill -9 $TOPPROCESS
  echo system overloading!
  echo Top-most process killed $TOPPROCESS
  echo load average is at $CPU_LOAD
  echo 
  echo Active processes...
  ps aux r
 
else
 echo
 echo no run-aways. 
 echo load average is at $CPU_LOAD
 echo 
 echo Active processes...
 ps aux r
fi
exit 0
