I am running magento 2 (2.2.1) on nginx and enable the cronjob by default.
php bin/magento cron:install
I don't customize any configuration regarding schedule of cronjobs.
after running the machine a few days, i saw that mysql service is always nearly 30-40% usage and machine is running a lot of "php7.1" processes
i reboot the machine and the error is the same, right now there are only a "few" php7.1 processes but it continue to raise
I already checked the logs, no errors there or exceptions.
I only found an issue on m2 backend
this indexer is always not "up to date"
can you please give me a hint how i can fix this problem?
attached a screenshot from the crontab
