Comments: | By: Benjamin (bulkorok) 2013-02-06 07:00:57.908-0600 backtrace output of core-dump Some numbers cleaned out By: Kinsey Moore (kmoore) 2013-02-06 07:55:23.849-0600 Please attach more information about the fax session, fax configs, relevant sip config snippets to the issue if you have them. If you have the core for this crash, could you print the value of f->data.ptr ("print f->data.ptr")?

By: Rusty Newton (rnewton) 2013-02-14 10:12:46.523-0600 Just talked with Benjamin on IRC - more debug (pcap and full log) coming tomorrow. By: Benjamin (bulkorok) 2013-02-19 08:23:42.353-0600 some data.ptr extractions. still waiting for next segfault. By: Rusty Newton (rnewton) 2013-02-26 16:27:54.599-0600 Setting this in 'waiting for feedback' until we get some pcaps or logs showing what happens right before the crash. Be sure to hit "Send Back" when you update. By: Benjamin (bulkorok) 2013-03-14 07:01:22.006-0500 Hi, finally I have a coredump with a pcap and a cli-capture. I added a screenshot (without numbers) from the flow of the fax-session that is shown in gdb bt. flow.png Additionally I can say that 2 seconds before another call to the same number came in. cli.txt shows the cli-output from the incomming calls. (gdb) print f->data.ptr $1 = (void *) 0xb By: Walter Doekes (wdoekes) 2013-05-25 07:23:51.501-0500 Benjamin: are you able to capture a pcap surrounding the crash? See tcpdump and file rotation.
