By: Roy Sigurd Karlsbakk (rkarlsba) 2006-03-06 13:45:20.000-0600 there are a handful sip clients in sip.conf, such as the pstn gateways, but all clients are fetched from realtime. we use realtime caching, yes By: Serge Vecher (serge-v) 2006-05-01 15:23:42 rkarlsba: are you still experiencing crashes here? By: Roy Sigurd Karlsbakk (rkarlsba) 2006-05-01 17:48:02 not recently please keep this open By: Roy Sigurd Karlsbakk (rkarlsba) 2006-05-07 08:19:00 Got another one last friday. same stuff happens. see attached bt By: Andrey S Pankov (casper) 2006-05-07 09:15:17 I am a bird, I can fly! How this is related to the first crash as well as to the second? If you are using gcc >= 4.0 please build your asterisk with 'make dont-optimize' and then report. And please do not mix everything in one issue. This is not your _personal_ support page, this is a bugtracker!!! Could you see it crashes in _different_ functions, even both are in chan_sip. Can you confirm you are running the latest SVN 1.2 branch >= r25323? What gcc version/distro/platform? I'm sorry I am so brute... but it should be clear enough asterisk bugtracker is not a support forum for FC4+ based distros and their buggy compilers.

I haven't come across any....... Also, please note that the system is in production and can't be upgraded too often. roy By: Andrey S Pankov (casper) 2006-05-07 12:24:41 Anyway please build at least 1.2.7.1 (if you are unable to get a fresh copy of SVN 1.2 branch) dont-optimize. Maybe a x86_64 issue as well. I can't see how this can be related to app_monitor. Are you using debian's bristuffed version? You need to compile asterisk from the sources provided by asterisk.org/digium.com. If you are using debian specific package please try to file a bugreport to their bugtracker. (Am I right? Please correct me if not.) By: Roy Sigurd Karlsbakk (rkarlsba) 2006-05-07 12:32:49 The distro is Debian Sarge, but asterisk is all compiled from the source. Do you know any relevant fixes in 1.2? I'm RoyK on IRC at #asterisk roy By: Serge Vecher (serge-v) 2006-05-07 12:48:19 >wait, what's app_monitor? I only see app_mixmonitor in the sources ... ok, answered by own question, it's in res_monitor not app_monitor. roy: could you please try to replace Monitor with MixMonitor in your dialplan? I remember reading that Monitor is going away in the next stable in favor of the latter. By: Andrey S Pankov (casper) 2006-05-07 12:51:16 Lots of fixes there... and lots of them may be relevant... By: Andrey S Pankov (casper) 2006-05-07 12:56:17 Your 2nd crash is easy to fix. as you can see "retrans_pkt (data=0x0)". Then you have "struct sip_pkt *pkt=data,". That's obvious it will crash at "ast_mutex_lock(&pkt->owner->lock);". But we need to now _WHY_ data==NULL since it never should. By: Serge Vecher (serge-v) 2006-05-16 09:39:24 alright: I think this bug ready for closure. Nobody else is experiencing this particular crash in chan_sip. Perhaps the root of the cause is the rtp-jitterbuffer patch, in which case the discussion needs to continue in that bug report. roy: if you are able to reproduce this problem on an unpatched stable branch with rev > 27000, please reopen the bug with non-optimized backtrace attached. thanks! |
