Comment (by j3gaming):

 I figured out how to trigger this 100% of the time, which also ends up
 deleting 1 or multiple cron tasks.

 Environment:
 Linux, with linux system crons running once a minute (crontab -e)
 Webmin
 PHP 7.4
 Wordpress 6.1.1 (DISABLE_WP_CRON = true)


 Within webmin, run a database backup. This usually takes ~5 minutes to
 complete for my website. Doing anything that would generally freeze/stop
 the website & database would probably work

 During that time, the linux cron will run. The result is this error
 message and 1 or more cron jobs being deleted.
