cron job disappearing

Hello

I have a drupal 8 website and I need to run the drupal cron every night at midnight
So I created a cron job into cpanel that looks like this:

wget -q https://xxxxxxxx.com/cron/xxxxxxxxxxxxxxxxxxxxxxxxxx > /dev/null 2>&1

The issue is that the crob job ends up disappearing from the cron job list after a few hours. If I go back to the cron page on cpanel, shortly after I created it, I'm likely to see it there but after a while the list becomes empty.


It used to stay there for several days and then it would trigger and do what it is supposed to do at midnight and it would disappear after a couple of days. Now it just disappears within a couple of hours.


I got our helpdesk guys to look for any memory issue but there was none. They checked the cron log and found this:

[root@cpanel log]# grep DELETE cron
Apr 15 04:13:38 cpanel crontab[20456]: (user) DELETE (user)
Apr 15 06:25:35 cpanel crontab[29287]: (user) DELETE (user)
Apr 15 08:34:37 cpanel crontab[7709]: (user) DELETE (user)
Apr 15 10:08:30 cpanel crontab[10504]: (user) DELETE (user)

Apr 15 16:40:30 cpanel crontab[30434]: (user) DELETE (user)

Apr 15 20:09:37 cpanel crontab[11104]: (user) DELETE (user)
Apr 15 22:23:07 cpanel crontab[25325]: (user) DELETE (user)
Apr 16 00:21:54 cpanel crontab[31848]: (user) DELETE (user)
Apr 16 02:25:58 cpanel crontab[6815]: (user) DELETE (user)
Apr 16 04:14:00 cpanel crontab[9004]: (user) DELETE (user)
Apr 16 06:17:29 cpanel crontab[15206]: (user) DELETE (user)
Apr 16 08:20:05 cpanel crontab[22374]: (user) DELETE (user)​

But they don't have a clue of what's happening and they kind of have given up....

Any idea someone of what could be wrong?

Many thanks for your help.

Thanks for you answer.
It is clearly not somebody who manually deletes the job. First because the people who have access to the account know about my issue and therefore would have raised it/stop doing it. And also because this happens at random time of the day inluding in the middle of the night.

One suggestion that I received is that may be crontabs for multiple sites are using the same file and clashing? Does that make sens to you?

Thanks

 

I've just noticed another thing.

I had changed the email cron sends the reports to from the default user to my own email and it has reverted to the default user. email. So it's not just that the cron job disappears, it feels like the whole cron thing is resetting to default values of default user and empty list.
