[asterisk-users] asterisk crashed on segmentation fault

[Arjan Kroon | Mobillion]

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,
