asterisk users - Nov 2007 - What do you do to keep asterisk alive?

I've asterisk stop (presumably segfaulting) a couple of times, and I was
just beginning to look at how to keep it running - what have others
done? 

I was thinking of wrapping a script around asterisk like this:

while 1
do
  asterisk -f
done

try "true" or ':' for the smily effect :-)

And if Asterisk decides to die? If you have a wrong module in
/var/lib/asterisk/module ?

You're reimplementing safe_asterisk badly. And safe_asterisk is bad
enough as-is.

Doing so you won't be able to stop asterisk, if you wanted to..

IMHO it's better to build a FSM (Finite State Machine) that handles the
Asterisk process and other collateral processes (like the MAPI proxy) and let
it monitor the process.

Moreover, you should make this FSM sensible to UNIX signals in order to
start, stop, restart Asterisk easily if you want.

HTH,

Have a look at the safe_asterisk script, which should automatically be
in /usr/sbin/safe_asterisk. It does this automatically, including emailing
a notification (if you set the NOTIFY variable).

Check the script's invocation of asterisk and make sure it includes the -f
option. This in included in 1.2.19 onwards and 1.4.5 onwards.
See http://bugs.digium.com/view.php?id=9121 for details if needed.

Monit <http://www.tildeslash.com/monit/> does the job really well.  It
certainly isn't a replacement for fixing the root causes of whatever
that makes asterisk die, though.

Why is it stooping on you? What version are you running? Are you
running any AGI scripts? I have asterisk running for months unless I
stop it manually it just doesn't die, specific system is with a quad
PRI cards using 3 of them, but just one for a PRI the rest to channel
banks. The other busy system that I have has 2 TDM400 cards and a dual
span PRI card. All Digium cards. I have other systems - though not as
busy - that run and die only when I issue stop now in the CLI or
shutdown on console.
