Summary:                    Asterisk crashes on reload of pbx_config.so
Description: 
After a recent upgrade from 1.2 to 1.4 we are getting intermittent crashes
when we issue a "reload pbx_config.so" from the asterisk console.  Notably,
our dialplan is quite large (http://bugs.digium.com/view.php?id=8#50MB).  This
did not appear to be a problem
under 1.2.  bt and bt full attached.  Since its not always re-producible,
I'm hoping that someone the bt will prove useful / informative to someone.

I'm pretty sure there weren't 2 reloads going on simultaneously.

I've been trying to reproduce this issue, and its definitely not trivial
to reproduce.  We've had a lot of weird crashes since upgrading from 1.2 to
1.4, and only on our production servers that are under load.  My suspicion
is that there is some sort of underlying memory issue that is manifesting
itself in different sorts of ways.

I'll see what I can do about the sanitizing our files for you, but this is
going to be a bit of a job in and of itself.

Its a little off topic, but I wanted to ask your opinion.  Given the size
of our dialplan, reloads, particularly of chan_sip are causing some
problems for us.  It seems that asterisk stops processing sip for some
amount of time during reloads.  This causes weird dialing behavior for our
end users trying to make / recieve calls during the reloads, and some of
our sip endpoints start re-registering to other, backup servers when the
reloads occur.  Do you have any suggestions / thoughts on this?  I was
going to start looking at realtime as a possible solution, but given the
size and complexity of our dialplan, and integration with our existing
backend systems this is probably not going to be a quick fix.
