[Asterisk-Users] bristtuff segfault

[Jean-Denis Girard]

Hi list,

I'd like to have comments from the bristuff / QuadBRI users, others are 
welcome to as I'm really lost and need to move on.

I have the following setup: a first asterisk is connected to the legacy
Alcatel PaBX to connect to a remote site with a second asterisk server.

                    PSTN
                     |
Legacy phones == Alcatel Omnipcx == Asterisk1
                                         |
                                         | IAX
                                         |
                                   Asterisk2 == 25 SIP phones

Both servers are dell 400sc (Pentium(R) 4 CPU 2.80GHz, 2 IDE disks in
software RAID1). The system has been working flawlessly for a week with 
4 analog lines between the omnipcx and asterisk1 (using TDM04B).

Now I've moved to a 4 BRI link between omnipcx and asterisk1, using 
QuadBRI from Junghanns.net. It does work... for about 3 minutes, and 
then asterisk segfault after hanging up a successful call to the omnipcx.

Backtrace shows the error is in libpri function q931_destroy (q931.c: 
1908), which is coherent with crash after hangup.

Asterisk / Zaptel / Libpri / Qozap on first server have been built with
the scripts from bri-stuff-0.1.0-RC4a.tar.gz. On the card, I only 
changed all groups of 5 jumpers to NT mode. Linux Distro is 
Mandrake-10.0. I tried with kernels (from kernel.org) 2.6.8.1 and 2.4.27 
with and without SMP, and got exactly same results.
(more details below)

Any hints would be much appreciated.

Thanks for a prompt reply.
Jean-Denis

Loading qozap shows no error except for devfs, but I doubt this is the
source of the problem:
