   It looks like you gave the solution in your post, note:

   The difference is Ubuntu allows a much higher hard limit.

   The beauty of Linux (and Unix systems in general) is that almost all   
   'settings' short of replacment of the kernel binary itself can be   
   changed without rebooting.  Unlike that other OS that requires a reboot   
   after each change in it's tabbed, checkbox filled, native configuration   
   UI.   
      
   In a root shell do:   
      
   ulimit -Hn 1048576   
      
   Then, from that same shell, "su -" to the user you are running this app   
   as, and that shell should inheret the new setting from the root shell   
   where you made the change.   
      
   As to which /etc file to edit to make it a permanant change I'd have to   
   'google' around for that one.
