nginx uLimit 'worker_connections exceed open file resource limit: 1024'

Solution 1:

Set worker_rlimit_nofile 65535; in nginx.conf within the main context.

Solution 2:

Become the user:

su - nginx

Check the limits:

ulimit -Hn
ulimit -Sn

Edit the number of files the file system will let you have open:

vi /etc/sysctl.conf
fs.file-max = 70000

load your changes:

sysctl -p

See if that helps.
