Some notes regarding the asterisk monit configuration:<br>

If you use systemd, this ulimit will have no effect: when you restart a<br>
service, it is restarted from a separate systemd context (cgroup) and<br>
not directly under your own.<br>
<br>
It would generalyl be a good idea not to embed such settings in your<br>
scripts and rather put them in a proper configuration file. What happens<br>
in you happen to run '/etc/init.d/asterisk restart'? It seems that \
all's<br> well, until you're suddenly out of file descriptors.<br>

Nice.<br>
<br>
Also: what happens when you run 'core stop now' from within asterisk?<br>
