Trying to get the equivalent of ulimit -n 20000 on a high load web server, however the /etc/security/limits.conf on ubuntu hardy doesn't seem to stick.
here is what I set in the config file.
root soft nofile 20000 root hard nofile 20000 www-data soft nofile 20000 www-data hard nofile 20000
I also tried
* soft nofile 20000 * hard nofile 20000
after rebooting, when i run ulimit -n on root, or www-data or my regular user i still see the default 1024.
