I'm setting up nginx from what I've understood the worker_connections value must not exceed the maximum number of open file descriptors retruned by ulimit -n.
On my fresh 16.04 ubuntu installation ulimit -n return 1024 which is very low comparing to what cat /proc/sys/fs/file-max -> 3269456.
1) Does those two values are related ?
2) If yes by which factor should I divide the value returned cat /proc/sys/fs/file-max to have a safe ulimit and worker_connections value ?
