Hi,

# cat croncheck.sh

#!/usr/bin/sh
while true
do
if [[ $(UNIX95= ps -H -C cron -o pid= | wc -l) -lt 1 ]]
then
echo "cron restarted:\n$(date)" | mailx -m -s "cron restarted!" root
/sbin/init.d/cron start
fi
sleep 120
done
exit

Change 120 (2 minutes) to whatever interval you wish. For obvious reasons, you cannot schedule this script to run via cron. Instead, use 'nohup':

# nohup croncheck.sh > /dev/null 2&>1 &

Hi,
so you did not like the:
MYPROC=sendmail
COUNT=$(UNIX95=1 ps -C $MYPROC -o pid= -o args= | wc -l)
if [ $COUNT -lt 1 ]
then
/sbin/init.d/$MYPROC start
fi

example in the second link given?

Change the sendmail to cron and you had your solution.
