In addiction to above, there are some systemd systems which might not use the /etc/security/limits.conf correctly.
For these, edit the systemd service file(s) 
systemctl edit name.service   ( which created the override file in /etc/systemd/system/name.service.d/override.conf _ 
systemctl edit --full name.service   ( which created the copy of the file in /etc/systemd/system/ ) 

And add whats needed. 

[Service]
LimitNOFILE=8192:16384


This is handy to have.
