Nginx + php-fm

Hello guys,

I've recently configured a LEMP environment on an ArchLinux VPS and I'm having problems with my websites where it's not always loading, specially images.

I'm running off of Linode (Linode 2048)

I have taken some screenshots;

I randomly get this while navigating through Xenforo:

http://d.pr/i/QWqg

http://d.pr/i/pgxk

Or images won't load:

I currently turned off Xcache and Memcached to rule out caching problems, but no luck yet. It Also happens on my othe non xenforo pages.

Any ideas? Your help is appreciated!

Thanks!
