asterisk users - Oct 2012 - asterisk crashed on segmentation fault

Hello,

I have a problem.
One every couple of months my asterisk system crashes with a segmentation fault.

kernel: asterisk[20527]: segfault at 0000080000000008 rip 00002aaac952d8f2 rsp
0000000040edb910 error 4

(This is in /var/log/messages)

If I look at the same timestamp in the warning log file of asterisk
(/var/log/asterisk/warning),
I see that the are warning about fix up channel:

Does anybody know what these messages mean?

I use the following drives and asterisk:
Asterisk 1.6.2.12
libpri 1.4.11.4-1_centos5
dahdi linux-2.4.0-1_centos5
We are using two Digium, Inc. Wildcard TE420P quad-span T1/E1/J1 card 3.3V
(PCI-Express) (rev 02)

Kind regards,

Normally if you are getting a segfault, that's a good reason to file a bug
report. However...

Using an old, unsupported version of Asterisk means that approach would probably
be fruitless.
I'd recommend you consider upgrading to either 1.8 or 11 at this point. If
you absolutely must
stick with 1.6.2 for whatever reason, then you can use 1.8 on a test system to
see if you can reproduce
your problem and if you can, file a bug report against that and hope the patch
either translates
well to 1.6.2 without much intervention or you could attempt to backport it
yourself if it doesn't.

Good luck with your problem.
