limit nofile has no effect?

[pablo platt]

I'm using upstart to start an erlang web server.
I'm using limit nofile to increase the number of allowed file descriptors
but when checking the limits I'm still seeing the default.
I'm getting errors for too many open file descriptors.

Am I doing something wrong?

When increasing the nofile in the /etc/security/limits.conf file, the errors
goes away:
* soft nofile 30000
* hard nofile 30000

I'm checking the beam (the process that is running the erlang vm) with:
pidof beam
cat /proc/<pid>/limits
...
Max open files            1024                 4096                 files
...

the upstart script:
--------------------------
limit nofile 20000 20000

start on (local-filesystems and net-device-up IFACE!=lo)
stop on runlevel [016]

export HOME=/var/lib/myapp


script
    exec sudo -u myapp -i myapp start
end script

pre-stop script
    exec sudo -u myapp -i myapp stop
end script
