High CPU

[Time]

Hey team.

Iwonder if someone can help me understand an issue I am seeing. My site s hosted in a dedicated server (8CPU, 64GB RAM and SSD disks),

The issue is that the CPU is constantly at %100. I notice that if I rename .htaccess to old.htaccess the CPU spike drops (but then obviously the site no longer works).

I don't think this is an issue with Chevereto per se, more than likely there is a loop in a process (apache, or PHP)somewhere, so I was hoping that someone could point me in the right direction.

The offending process that is stealing the CPU is PHP-FM

Hello,

Usually it means that your server is under an attack from vulnerability scanning bots. They try different URLs of known vulnerabilities to exploit them. And since the probed scripts/files are missing on your server requests are processed by a CMS engine (thanks to .htaccess). Too many requests to PHP+MySQL cause a critically high CPU load. I see this pattern on many servers nowadays.
