Hi There,

Since this morning I am experiencing high CPU loads which is causing my site to go up and down. Since I am hosting real-time football data (which is collected on a different droplet) this is a big issue since the EURO starts within 2 hours.

I already pinned up a new droplet which gives me the same problem. The CPU load is between 1.19 and 3.5 currently.

I have really no clue what to do about or were to look why this is happening. My site worked fine for over 2 months and all of a sudden this problem occurs.

Is there anyone that can help me with this? I have sinned up the server using travel forge BTW.

Regards,
Ronnie

Run the command "top" from console and it will show you what process is using CPU. That would at least be the best place to start. It could be a number of different things.

    Your PHP usage is too high. There must be a php script that is in a loop or somehow running too much. Try restarting your http service and see if the cpu decreases (check it right away, it may go back up again)
