When I do
crontab cronfile
and then checks crontab -l everything looks good. The cronjobs are there as they should. Then I leave it, hoping it to stop a process at 11.30 pm and start it up again at 06.00 am. When I am back in the morning, if I then do crontab -l, it is empty. And nothing have happend during the night. The comuputer is running but the crontab disappears. How can this be, I do not have access to var/spool/cron/crontab, so I cannot verify it there.
Help please, anyone.
