Did you try setting a minimally changed limit instead? – Josip Rodin Jul 09 '16 at 22:32 — Josip Rodin, Jul 09 '16 at 22:32

I found that if the service is launched under an upstart init script you must use the stanza limit to control this!

If u set root hard nofile 65535 it will only change root users limit. If you want to change another users limit add that users username for example,

sharewind hard nofile 65535 Or add * for username which will change all users limit. But it is not recommended.

It doesn't work – sharewind May 08 '14 at 01:54
Did you change both soft and hard file limits. If not add the soft file limit too. I used hard limit only as an example – Manula Waidyanatha May 11 '14 at 09:17
I have the same experience as @ManulaWaidyanatha – Jeune Jan 27 '15 at 07:47
