I created a WordPress droplet from Marketplace.

After some time, some proccess appears and starts consuming all CPU from my server.

This process does not stop, only if reboot.

Depending on your admin settings, you’re likely being crawled by one of the many search engines out there. That’ll peg the CPU of most small droplets. I’d start looking at your Apache/Nginx logs to see where-from and what-type of traffic is hitting your WP server.
