The hard limit you're seeing is capped by the sysctl fs.nr_open value. If you want to increase the hard limit, you first have to increase the sysctl value. unicorn:~$ sysctl fs.nr_open fs.nr_open = 1048576 unicorn:~$ sudo sysctl -w fs.nr_open=2097152 fs.nr_open = 2097152 unicorn:~$ ulimit -Hn 1048576 unicorn:~$ sudo -s unicorn:~# ulimit -Hn 1048576 unicorn:~# ulimit -Hn 2097152 unicorn:~# ulimit -Hn 2097152 To make these changes permanent, you'll need to put the new sysctl value in /etc/sysctl.conf (or some equivalent file). I'm not sure if that'll do the whole job by itself. You may also need to set the hard limit value in /etc/security/limits.conf -- but I'd try with just the sysctl change first, and see if it works following a reboot.
