1) Add line
* hard nofile 51200
to /etc/security/limits.conf
Note: The * means every user except root
Note: 51200 represents the number of concurrent open files. This number must by a multiple of 1024
2) Add line
session required pam_limits.so
to /etc/pam.d/common-session
3) Stop all processes that need the new limit
4) Restart SSH server
5) Login again
6) Run ulimit -a to check the values
7) If the values haven't changed, reboot and try step 6 again
8) Start new processes from command line

Most other tips about increasing the limit only mention ulimit but leave out the pam steps.
This one actually works!
Thanks!
