Crond dies often and enters into dead state

Prabagaran · 05-16-2011, 02:37 AM

Hi,

I have set cron on my Fedora 8-64 bit, which was running without any issues, till a couple of months ago.

Suddenly, it started to enter into dead state often (say once in a week, somtimes once in two weeks).

I have to manually restart the crond daemon to start the cron jobs.

Would be pleased if some-one guides me in right way to troubleshoot and resolve this issue, permanently ?

Regards,
PL

Hi Prabagaran,

If I was in your place, I would have used the below script and run it as a daemon as root user.

You can follow the below steps.

Code:

vim /root/cron.sh
while true
do
pgrep crond &>/dev/null
if [ $? -ne 0 ]
then
service crond start
fi
sleep 30
done

chmod 700 /root/cron.sh

nohup bash /root/cron.sh &

Also, to make it last across reboots append the below line in /etc/rc.local

Code:

nohup bash /root/cron.sh &

This script will check for the cron service (crond daemon) after every 30 seconds and if the service is not running, it will start the cron service.

Hope this helps.

I wonder why it died. Anything in the logfiles in /var/log?
