So I've been having this issue for a long time now, but I ignored it because I just rebooted nginx/php-fpm and it went away, for a bit. Today, that didn't work! I'm running Xenforo 1.3.2, and it's just bailing on anything that works via post. For example, if you use More Options when editing a post, that will time out. Same with avatar uploads, template editing, etc. I don't know what to even attempt anymore. I've spent the entire day Googling (and most of the results involved overloaded servers, my load avg is 0.00). I've also spent a good 2 hours looking around the various logs (domain + system ones). It doesn't even show PHP timing upstream like I thought it would! I should mention the rest of the site is super quick and painless. I even tried recompiling both PHP and NGINX. Can anyone suggest anything? I'm fresh out of troubleshooting ideas.
