Setting Ulimit

I never found a solution to do it live (nothing worked that I found) so it looks like a relogin is required.

Check your maximum file limit

 cat /proc/sys/fs/file-max
824460

 

This is different than your actual's user limit which you'll see below

ulimit -n
1024

Try and set it higher but it won't work

ulimit -n 65000
-bash: ulimit: open files: cannot modify limit: Operation not permitted

Set system wide defaults

sudo vi /etc/security/limits.conf
*             hard    nofiles           600000
*             soft    nofiles           500000

Making it live from a shell session (it won't work for your GNOME/XWindows session itself)
sudo su
root@homebox:/home/one# ulimit -n
1024
root@homebox:/home/one# ulimit -n 60000

ulimit -n
60000

root@homebox:/home/one# ulimit -n 60000
root@homebox:/home/one# ulimit -n
60000
root@homebox:/home/one# su - one
one@homebox:~$ ulimit -n
