Some notes regarding the asterisk monit configuration:

If you use systemd, this ulimit will have no effect: when you restart a
service, it is restarted from a separate systemd context (cgroup) and
not directly under your own.

It would generalyl be a good idea not to embed such settings in your
scripts and rather put them in a proper configuration file. What happens
in you happen to run '/etc/init.d/asterisk restart'? It seems that all's
well, until you're suddenly out of file descriptors.

Also: what happens when you run 'core stop now' from within asterisk?
