In my crontab, I have set MAILTO and a bunch of cron jobs (5-10 jobs).
These cron jobs usually run fine and I get emails for them. Most of these jobs consistently run as expected. Emails and filesystem results verify this.
Two of these jobs sometimes don't run, or don't complete as expected. I receive no email and the filesystem doesn't show any results.
What could cause this? The system didn't reboot, so it should have been running at the scheduled times. At least, how come there was no email?
If it makes any difference, this is on Fedora 15 Linux.
