Job for asterisk.service failed because a timeout was exceeded.
See "systemctl status asterisk.service" and "journalctl -xe"
for details.

As you can see it's still working. If I then connect to the console
asterisk is running fine, in this case Asterisk restarts randomly (every
1-2 minutes). If I then start asterisk myself by doing:
/usr/sbin/asterisk -g -f -U asterisk
Then it starts fine and works with no issue. It would seem there is
something with systemd that is causing Asterisk to restart. I don't think
it's the actual script since I would then expect it to always restart at
the same time though I am not able to find any dumps any where on the box.
Any ideas?
