[Asterisk-bsd] Reliability

[Tim St. Pierre]

I'm not much of a programmer, so I haven't taken a crack at it a core dump.  

I was trying some creative logging to find patterns though.  It looked like it 
would get panicky when Meetme rooms closed, or if I did a pickup through a 
local channel (pickup was trying to re-invite, even though canreinvite=no), 
so I used to direct it through a local channel to get around that.

Putting the Zaptel card in seemed to help a lot.

I haven't had a core dump since I removed the pickup through local, but I'm 
still getting erratic behaviour at times.  

If I do a sip show channels, I get 100 or more channels, mostly SUBSCRIBE.  I 
could have 40 for one extension, that only has 7 subscriptions on it.

I have the entire overseas rate table listed as part of the dialplan, which is 
fairly large.  I would like to move that to a database lookup, but I haven't 
figured out how to do the pattern matching with a variable length key (some 
country codes are longer than others).

I have 1.4.17 installed on a fresh DL360 (same specs, just fewer drive slots), 
and I am debating whether to move everyone to that machine (It would be phone 
only), or to rebuild it with Linux.

If everyone else out there has been doing high volume production setups 
without issue, I would love to stay with BSD.  As far as asking for help with 
crashes and strange things, what info is useful to post?  

Thanks

-Tim
