Cron stopped working but cronlog stays empty

Kjanss · 04-04-2012, 03:24 AM

I run CentOS 5.8 /32, I haven't done anything on the box (except regular yum updates).

Something strange is happening to me:

Since a couple of months my cron works partially. One entry in my bash script, a 'service restart' doesn't seem to be executed anymore. The cron log stays empty (0 bytes)

Is there any way to find out what happens?

have you disabled the crond deamon?

If there is an error in the cron file, cron fails. In my distribution, cron error messages are disabled by default.

Well, assuming crond is running, normally it will email the owner of the job or root user if it has an issue.
Try the mailx cmd as each user and see what's there.
Also, /var/log/messages?

in /etc/syslog.conf I read:

Quote:

# Log cron stuff
cron.*

/var/log/messages are empty, as well as /var/log/cron

The /etc/cron.d directory has a file called
cron_maintenance
containing

Quote:

* * * * * root /root/maintenance.sh

/root/maintenance.sh runs fine, except one line where I restart a service:

Quote:

service pdns restart

When I ssh under root, I run

Quote:

-bash-3.2# service pdns restart

without any problems

Putting the restart in a seperate cron
/etc/cron.d/cron_pdns

Quote:

0 * * * * root service pdns restart

Also doesn't seem to work
