[o_AF]

Hey! I have been getting a weird crash in my server.
I have a dedicated server running Ubuntu Server 17.10 (in the OS instalation menu, under linux i selected Ubuntu Server 17.10) and everything is running good, untill it crashs.
This error shows up and I have to restart the server

I was wondering what is the best OS to run this servers, I have a lot of choices (I have more than this, I just heard of this ones)

Wich one is the best? Im kind a noob at this stuff.
Tnanks for your time.
