Firstly, look and see what the "too many open files" are:

# lsof -p94218

(or whatever the complaining PID is). I'm assuming FreeBSD has lsof.
I don't know, as I use Linux.

Next, examine the cron jobs that happen at 2am, to see if any of them
could explain anything.

Failing that, it could be that something ishappening at your provider
everyday at 2am and Asterisk is not coping with it gracefully.

You could also try specifying 212.187.162.178 temporarily instead of
voipfone.co.uk - that would tell you whether the problem is DNS related.
