I am running discourse v2.1.0.beta4 +6 with the docker installation on an Ubuntu 16.04 with 2CPUs and 4GB of RAM.
This is no heavy load forum, the average load is 0.11 0.06 0.01.
But sometimes when I visit the site, the html page is not correctly formatted. It looks like CSS files are missing.
I took a look inside the container and I am wondering, if it is nginx, that stops issuing files - I get messages like this in the error log:
2018/05/11 23:04:12 [error] 310#310: *4831 limiting requests, excess: 12.044 by zone "flood", \ client: ....., server: _, request: "GET /t/name-of-issue/647 HTTP/1.1", host: "....."
It seems like it is due to the
limit_req settings in
/etc/nginx/conf.d/discourse.conf. Can I change these settings without them being overwritten after an update? Or what would be the requested way to deal with that problem?
