| Description: | System is asterisk 1.8.7.0 (Asterisk 2.2-rc1 packages). Call comes in through DAHDI (PRI) to an agent (SIP). Agent parks the call. After a while releases on it and parks it again. Repeating this 3-6 times leads to a crash at the time of parking: #0 0x007cfc2d in pthread_mutex_lock () from /lib/libpthread.so.0 #1 0x00719ca6 in pthread_mutex_lock () from /lib/libc.so.6 #2 0x0817c174 in ast_sched_runq (con=0x0) at sched.c:605 #3 0x08101e64 in waitstream_core (c=0xc174b98, breakon=0x81bbc6e "", forward=0x81bbc6e "", reverse=0x81bbc6e "", skip_ms=0, audiofd=-1, cmdfd=-1, context=0x0) at file.c:1208 #4 0x0810240a in ast_waitstream (c=0xbc0c110, breakon=0x81bbc6e "") at file.c:1332 #5 0x08167e78 in say_digit_str_full (chan=0xbc0c110, str=0xb4848294 "701", ints=0x81bbc6e "", lang=0xbeee8af "en", audiofd=-1, ctrlfd=-1) at say.c:261 #6 0x080af97d in ast_say_digits_full (chan=0xbc0c110, num=701, ints=0x81bbc6e "", lang=0xbeee8af "en") at channel.c:8062 #7 ast_say_digits (chan=0xbc0c110, num=701, ints=0x81bbc6e "", lang=0xbeee8af "en") at channel.c:8034 #8 0x080fb6c3 in park_call_full (chan=0xb615bc50, peer=0xbc0c110, args=0xb484a728) at features.c:1499 #9 0x080fbfbe in masq_park_call (rchan=0xbc0c110, peer=0xbc0c110, timeout=<value optimized out>, extout=0x0, play_announcement=0, args=0xb484a728) at features.c:1601 #10 0x080fc271 in manager_park (s=0xb484b1b0, m=0xb484af70) at features.c:6899 #11 0x08126d93 in process_message (s=0xb484b1b0, m=0xb484af70) at manager.c:4530 #12 0x081287b3 in do_message (s=0xb484b1b0) at manager.c:4690 #13 0x081311f7 in session_do (data=0xb9a0028) at manager.c:4781 #14 0x08185a02 in handle_tcptls_connection (data=0xb9a0028) at tcptls.c:233 #15 0x0819217b in dummy_start (data=0x94d5f78) at utils.c:1004 #16 0x007cd832 in start_thread () from /lib/libpthread.so.0 #17 0x0070d46e in clone () from /lib/libc.so.6 The attached patch seems to be a work around: c->sched was already NULL (cleaned up at hanguup time?) | ||
| Comments: | By: Richard Mudgett (rmudgett) 2011-10-24 11:08:44.333-0500 See SVN v1.8 commit -r334840. That should have already fixed this issue. By: Michael Spiceland (mspiceland) 2011-10-24 11:16:00.522-0500 Tzafrir, this should be fixed by [r334840|http://svnview.digium.com/svn/asterisk?view=revision&revision=334840], which came after the 1.8.7.0 release you are reporting against. Can you retest with 1.8.8.0-rc2 and see if this resolves the issue for you? By: Tzafrir Cohen (tzafrir) 2011-10-25 08:20:08.220-0500 That patch fixed the crash, indeed. I missed it when looking at the log. Closing. By: Richard Mudgett (rmudgett) 2011-10-25 09:43:07.925-0500 Already fixed in v1.8.8-rc2. | ||
