1024 Connection Limit

[Alex Davies]

Hi All,

To answer my own question, the answer is to add this to the upstart file:

limit nofile 80000 80000
#limit nofile unlimited unlimited

I found that unlimited failed to work, so I just set a limit similar
to that of uname -n on my system.

It does seem the upstart default is 1024, regardless of ulimit. I am
not sure if this is a feature or a bug, but it caused me some
problems!

Many thanks,

Alex
