Magento 2 - PHP-FPM high CPU

[Badmintonplanet]

Hello,

We are running a Magento 2.3.4 installation and for some time now our FPM i draining our shop.
When people come to our shop and click away, our FPM goes as high as 100% with a few rows..

I've been bugtracking inside of our installation, but i can't find any errors.. system.log or update.log is not really helping in this case.

Cache is running and i'm on production mode

Is there maybe someone who had the same problem and fixt this problem.

Hello,

i saw some similar error with MariaDB. An updated solved this problem.

What do you mean by updating? You mean replacing MariaDB with for instance Mysql?

Or what doe you mean?

No, i updated mariadb to 10.2.x to solve the problem. 

Please have a look at the magento requirements for your exact version.

Ist there an varnish frontend cache installed and is full page caching enabled? Maybe there is an crawler scanning your site.
