Red Hat Enterprise Linux Server release 6.2 (Santiago)
64bit
Manual Install

Hello,

External commands has stopped working suddenly, without to change anything.

System component status have some components down (see attach), and pnp graphs are not drawing. I suspect it could be a permission issue, but apparently all permissions are correct...

Is crond running?

Code: Select all

service crond status
If it is stopped that may be the problem

Code: Select all

service crond start

Also, lets tail the cron log
