Getting 500 errors on osgeo7

[robe]

Just noticed it. Might be happening on trac as well.

Actually this is more than trac. I think it's osgeo7 since my alerts are going off on other sites on osgeo7

It was happening today during our nextcloud meeting. The error logs showing too many open files.

I upped the max open files limits

By adding these lines to /etc/security/limits.conf as sugested in

​https://serverfault.com/questions/1003364/nginx-500-24-too-many-open-files

www-data    soft    nofile   20000
www-data       hard    nofile  40000

Then adding at the top of /etc/nginx/nginx.conf

worker_rlimit_nofile 16384; 

systemctl nginx restart
ps -faux #using the root proc for nginx fill in below
cat /proc/<nginx-pid>/limits

And verified the settings took before the open files soft limit was 1024 after

I still need to verify if the /etc/security/limits.conf was really necessary as I don't think it should have been. It seemed without that putting in the worker_rlimit_nofile 16384; did not take.

I'll keep this open and monitor.
