Oh, don't mind me, I'm just running roughshod over your processes.

sak.sh

#!/bin/bash
#
# seek and kill a mem hog fork()'d child
#

SEEK="stud"
SNOOZE="6000"

while [ : ]; do
  echo Snoozing for $SNOOZE
  sleep $SNOOZE
  LINE=`ps auxwf|grep $SEEK|grep -v grep|tail -n+2|sort -nk6|tail -1`
  if [ -z "$LINE" ];
  then
    echo No proc
  else
    PROC=`echo $LINE | awk '{print $2}'`
    MEM=`echo $LINE | awk '{print $6}'`
    echo The $SEEK pid $PROC is using $MEM ... killing it.
    kill $PROC
  fi
done
