Hello,I recently noticed that there are over 8000 emails with exactly the same message:
There are no commands defined in the "setup:cron" namespace.
Did you mean one of these?setupsetup:configsetup:dbsetup:db-datasetup:db-declarationsetup:db-schemasetup:disetuperformance
I asked my service provider support and they replied thatapparently this cron job is causing the issue:
3,16,38,54 * * * * /opt/cpanel/ea-php74/root/usr/bin/php -d memory_limit=512M /home/store24slovenly/public_html/bin/magento setup:cron:run >> /home/store24slovenly/public_html/var/log/setup.cron.log
I didn't actually set that cron job up myself and am not really familiar.
Any assistance in addressing this error will be much appreciated.
You need to remove cron to stop emails related to errors. For more help, please do check https://github.com/magento/magento2/issues/29872.
