I guess, a cronjob can cause the problem. Make sure that cronjob doesn't running from non-authorised user, which hasn't access to Magento's files. By using this command you can display a list of the crobjobs by user, in this case magento is the username:

sudo crontab -l -u magento

To fix that, you can remove all the Magento's tasks from the list of cronjobs:

crontab -e

And installing them again:

bin/magento cron:install
