Issue
*/5 * * * * my command
This entry works but every 5 minutes it gets executed twice, why?
In /var/log/cron
it shows:
Jun 16 22:20:01 Test CROND[12512]: (root) CMD (my command)
Jun 16 22:20:01 Test CROND[12516]: (root) CMD (my command)
So it's not from two users.
It is only entered once with crontab -e -u root
. The command is a php command.
Solution
Nothing in the description gives reason for it to be executed twice. Look elsewhere.
- Do two users call it?
- Is it entered twice?
- Does it call itself?
- Does it set in motion conditions for repetition?
If it's a shell script you're executing, have it append whoami
and date
to a log file. You should be able to dig up the reason.
UPDATE
Type ps -A | grep crond
, make sure crond isn't running twice.
