Description:	i had several crashes today :-( after reading the logs found that at crash time all the logs belongs to a specific extension which is set on a snom190 sip phone. after restarting the phone everything fixed! ****** ADDITIONAL INFORMATION ****** ofcourse the main problem was from the snom phone, but it can be a potential bug in * when a buggy sip device can act as a DOS Attacker! backtrace and debug level 6 at crash time is attached.
Comments:	By: Olle Johansson (oej) 2005-03-07 09:24:27.000-0600 Please read the bug guidelines. We need quite a lot more information about your configuration and a SIP debug of when this happens. From the backtrace, it seems like the crash happened in chan_local, so we need to get your dialplan as well.

By: Clod Patry (junky) 2005-03-07 23:08:52.000-0600 DeadAGI(Hangup.agi,${DIALSTATUS},${ANSWEREDTIME},${DIALEDTIME},${HANGUPCAUSE},${CAUSECODE}) why passing all these vars? They aren't working in DeadAGI? By: paradise (paradise) 2005-03-07 23:33:59.000-0600 yes, you're right but at the moment DeadAGI just do some loggings for me. will this cause any problem? By: brc007 (brc007) 2005-03-08 02:11:22.000-0600 no, it shouldn't. By: Mark Spencer (markster) 2005-03-12 13:08:38.000-0600 can you please rebuild with -DDEBUG_THREADS and "make clean ; make valgrind ; make install" and then find me on IRC so I can poke around your core dump again?  Also, please update to latest CVS of course. By: paradise (paradise) 2005-03-12 14:53:36.000-0600 for sure i can do it, but my core dumps are made from a stable *. unfotunatly i couldn't make the snom phone to buggy state again!! By: Mark Spencer (markster) 2005-03-13 21:36:32.000-0600 Well, reopen if you can duplicate it.  Nothing we can do without it being able to be duplicated.
