idk what I have done to our Friendica but it shows a 502 Bad Gateway nginx error quite often....and is 7am....tired now, I added a few RSS sources from Reddit and that seemed to have fucked it up but I don't understand what. I removed them since...

The nginx error logs show stuff like 2021/08/02 07:05:57 [error] 2732#2732: *1092 upstream timed out (110: Connection timed out) while reading response header from upstream, client: ******, server: social.trom.tf, request: "GET /ping?format=json&uid=22&_=1627677955767 HTTP/2.0", upstream: "fastcgi://unix:/var/run/php/php7.3-fpm-friendica.sock", host: "social.trom.tf", referrer: "https://social.trom.tf/network"

EDIT: Seems to work better now after restarting the php-fpm...but I'll have to go to sleep...problem with Friendica (social.trom.tf) is that the database is so large I cannot restore it with yunohost...nginx fails (times out...). Anyways I hope will be ok. Will look more into it tomorrow. #tromlive

From my experience adding ton of rss accounts (bif and active) will cause lot of traffic and in return can put the instance down. Next time it happens, check how many fpm processes you have running and how many sql queies are running. If all child processes declared in your php config are in use, your site will be down until either they finish or you restart php.
