Hello,
I have a droplet with 2 CPUs and 4Gb RAM, and I have noticed that it is impossible for my droplet to go above 1.00 load average. If I hit 1.00 then the server will crash, and one or more servers will need restart: Php-fpm or nginx.

Can someone explain to me why it cant go above 1.00, do I have multiprocessor system or single core? Or maybe i set something worng?

It isn't the load average that is causing a system crash, as load averages can be 900+ and the system will still be online, though very slow. Most likely you are running out of RAM which is causing the system to hang. You are probably using more RAM than CPU, so you run out of RAM well before there is a high load on the CPU itself which is why your load average is low but the system hangs.

Try adding swap to your server and see what happens:
