Hi, yesterday I set up a WordPress server with 1GB Droplet for WordPress with 1GB separate droplet for Mysql Database.
Today I after I logged in to control panel I saw a sudden Spike in CPU and Disk IO and A sudden Fall in Ram after that. I checked my website its down server was frozen, I tried to ssh to the server and tried to restart the apache, nothing worked so I had to restart the server from control panel

this is the apache /var/log/apache2/error.log ->https://pastebin.com/7ZFx2d3T
