An acquaintance complained about something not running on their system and asked for some help. I did a
crontab -e and it mysteriously was blank! We were able to restore their crontab from a backup but she wants to find out what happened so they could take steps to avoid this happening in the future.
I checked history to see if someone accidentally ran a
crontab -r and that wasnt the case. Someone mentioned that if someone was editing the crontab while the system is rebooting could also cause its disappearance. Checked too and that wasnt the case, the box has been up for 20 days.
Anyone have any ideas what could have caused crontab to just up and disappear?
