| Comments: | By: Michele (mickyvoip) 2011-10-22 06:45:58.784-0500 The crash is due since the struct v is empty #0 0x00007f6cd6d812d0 in build_peer (name=0x104ecc0 "pippo", v=0x0, alt=0x0, realtime=0, devstate_only=0) at chan_sip.c:27097 (gdb) print v $3 = (struct ast_variable *) 0x0 The this call fails ast_log(LOG_ERROR, "Bad ACL entry in configuration line %d : %s\n", v->lineno, v->value); By: Paul Belanger (pabelanger) 2011-10-22 10:45:59.136-0500 Thank you for your bug report. In order to move your issue forward, we require a backtrace[1] from the core file produced after the crash. Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the Compiler Flags section, then: make install After enabling, reproduce the crash, and then execute the backtrace[1] instructions. When complete, attach that file to this issue report.

By: Michele (mickyvoip) 2011-10-22 11:01:00.487-0500 This is part of the sip.conf [pippo] type=friend username=testpeer secret=pippo host =chepipop.i port=5060 disallow = all allow = ulaw,alaw,gsm,ilbc,g722,g726,g726aal2,g723,g729 By: Michele (mickyvoip) 2011-10-22 11:36:50.649-0500 Backtrace By: Leif Madsen (lmadsen) 2011-10-31 13:54:40.399-0500 You're also using res_timing_pthread -- you shouldn't use that. Use res_timing_dahdi instead. At the very least use res_timing_timerfd in version 1.8.7.1 or later. By: Michele (mickyvoip) 2011-11-01 08:10:53.808-0500 I tried with the same result By: Walter Doekes (wdoekes) 2011-11-07 02:43:23.942-0600 Attached patch should fix it. (I added error=1 in case of enomem in main/acl, unrelated, but I was in the neighbourhood.) Regards, Walter Doekes By: Michele (mickyvoip) 2011-11-07 12:47:50.045-0600 Hi Walter yes with the patch the server does not crash However, something strange happen. After 6 hours asterisk was not able to register the provider. My bad, I did the mods and pushed to production I was not able to debug it, since my priority was to put everything online asap, I pushed the old version (1.8.5) | ||||
