Cron running but not working

[anomie]

You received the output email afterwards?

In my mind we've ruled out:

• common gotchas (incomplete PATH, cron.allow/cron.deny, permissions, etc.)
• dead crond daemon
• selinux
• syntactical problem in, e.g., your /etc/cron.daily scripts

Agree? Unless your system clock is going bonkers, I'm out of ideas for the moment. I do find it interesting that the problem started on one RHEL 5 machine, and then eventually crept into other (CentOS) machines as well.
