Hello, I am getting a bunch of error messages of this kind in my NGINX error log:
2021/01/16 13:40:45 [alert] 68769#0: *1 socket() failed (24: Too many open files) while connecting to upstream, client: 123.45.67.89, server: cloud.mydomainhere.tld, request: "GET /core/preview?blah=1 HTTP/2.0", upstream: "fastcgi://127.0.0.1:9000", host: "cloud.mydomainhere.tld" I am running a Nextcloud server with NGINX and PHP 7.3. Since OpenBSD Is quite conservative with open file limits by default, I assume that NGINX/PHP is running into this limit. I have already significantly increased 'kern.maxfiles' in sysctl.conf, but the problem persists after a reboot, leading me to believe that it is a login.conf limit that I am running into. Both PHP and NGINX are running as user 'www', which does not have a login class. Since I have not been in this situation before and struggled to find a pointer online, I'd be thankful if you could tell me the "recommended" or "best practice" way of doing this. - Should I simply assign a login class to user 'www' and then change my limits through that class? - Should I run the processes as a different user & login class? - Is there perhaps some other way to set limits just for specific processes? Thanks in advance for any pointers!
