Hi,

Regularly, I encounter the following problem :

[Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 1: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 2: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 3: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 4: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 5: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 7: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 9: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 10: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 11: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 12: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 13: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 14: Red Alarm [Sep 28 10:18:48] WARNING[13121] chan_zap.c: Detected alarm on channel 15: Red Alarm [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 1 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 2 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 3 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 4 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 5 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 7 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 9 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 10 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 11 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 12 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 13 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 14 [Sep 28 10:19:20] NOTICE[13121] chan_zap.c: Alarm cleared on channel 15

But after Asterisk has detected that access had returned, it is no longer operational… I must restart the asterisk service for this to work.

Here are the different versions, different elements have been introduced :

Debian :
Linux asterisk 2.6.27.10-grsec #1 SMP Thu Jun 18 17:19:40 CEST 2009 x86_64 GNU/Linux

Asterisk (paquet debian) :
Asterisk 1.4.21.2~dfsg-3 built by buildd @ nautilus on a x86_64 running Linux on 2009-01-04 21:26:06 UTC

Zaptel (paquet debian) :
ii zaptel 1:1.4.11~dfsg-3 zapata telephony utilities
ii zaptel-modules-2.6.27.10-gr 1:1.4.11~dfsg-3+1 zaptel modules for Linux (kernel 2.6.27.10-grsec)

My telecom operator said he did not see these cuts.

So I wonder if the problem is not the versions of software and drivers installed?

Thanks for your help !!

The problem comes from the parameter resetinterval in the file /etc/asterisk/zapata.conf.
voipphreak.ca/2006/03/12/pri … -warnings/

I would tell you if it works!

It doesn’t work…

Here are the problems encountered :

Nov 2 16:57:24 condrieu kernel: wct2xxp: Setting yellow alarm on span 1 Nov 2 16:57:24 condrieu kernel: timing source auto card 0! Nov 2 16:57:52 condrieu kernel: timing source auto card 0! Nov 2 16:57:57 condrieu kernel: wct2xxp: Clearing yellow alarm on span 1

And :

Nov 3 11:25:21 condrieu kernel: asterisk[32580]: segfault at 41d6a3d8 ip 00000000004923eb sp 0000000041d6a3e0 error 6 in asterisk[400000+f8000] Nov 3 11:25:21 condrieu kernel: grsec: From 89.31.144.72: signal 11 sent to /usr/sbin/asterisk[asterisk:32580] uid/euid:103/103 gid/egid:104/104, parent /sbin/init[init:1] uid/euid: 0/0 gid/egid:0/0 Nov 3 11:26:39 condrieu kernel: wct2xxp: Setting yellow alarm on span 1 Nov 3 11:26:39 condrieu kernel: timing source auto card 0! Nov 3 11:27:08 condrieu kernel: timing source auto card 0! Nov 3 11:27:13 condrieu kernel: wct2xxp: Clearing yellow alarm on span 1

Where the problem might come from?
