#fastcgi_pass unix:/var/run/php5-fpm. Try_files $uri $uri/ /index.php?q=$uri&$args
I can see in the htop that there is a lot of mysql process and start suspecting that something (wordpress or ?) is creating a bunch of unnecessary connections to mysql but I don't know how to investigate further. I changed multiple time the nginx and php5-fpm configuration without any durable change. I have followed multiple threads with similar problems nothing really worked, so I surrender and ask for help here. At the same time, you can reach conclusions about processing speed by checking the CPU temperature. And since yesterday it just all happened again, I noticed that if I restart php5-fpm or mysql the site is accessible again, but only for 5-10 minutes before giving a 502 or 504 errors again. If CPU usage is too high, users will experience long load and save times, and in the worst-case scenario, programs will start to freeze because the processor is overloaded with too many processing commands. At that time I decided to move to Nginx/php5-fpm, things went well no more 502, 504 errors for a while.
I first used Apache2, and after a few months running perfectly I suddenly started to got some 502, 504 errors. I have t2.site instance on AWS hosting a very low traffic personal website built with wordpress, nothing extraordinary. I'm struggling with this problem since quite a while.
