asterisk users - Mar 2009 - Script to softly restart Asterisk each midnight to clean locked channels

As Asterisk has inner problems and channels very often locks we have such
script to restart Asterisk each midnight.

 

We (our clients) mostly use v1.4.18.1. We can't upgrade to newer versions
because there are too much changes which would brake our system
(realtime/sip/iax2/cdr/etc/etc).

 

Script soft hangups all alive channels in dirty way then kills Asterisk and
starts it up. 

 

Hope it will be useful to somebody.

 

Corrections/comments welcome.

That is the things we must help to solve for not having to do to 
something like this on asterisk servers. Fortunately I use 1.4.22 
version which has proved to me to be quite stable, judging from this uptime:

System uptime: 1 week, 2 days, 19 hours, 22 minutes, 53 seconds
Last reload: 10 hours, 31 minutes, 33 seconds

Upgrading to 1.4.23.1 resulted in random core dumps (suspecting attended 
transfers issue) but unfortunately I've had no time to debug it and make 
a good bug report. My case is a 24/7/365 non-stop call center, so I 
didn't have another choice but to rollback.

I hope some of us just can help asterisk be better by trying to use the 
latest version at least on testing environments, to not having to 
maintain an "internal version" and cherrypicking patches that may or
may
not resolve the issues that we could experience.

Just my 2 cents...

Why restart Asterisk, free up the channel...
