| Description: | A few weeks ago asterisk started randomly segfaulting with 1.8.13.0 so I updated to 1.8.16.0. It always happens when the AMI originates a call, this is what the console log outputs, including 500 to 700 refcount errors on every single one of these crashes (it's happened 15 or so times now): [2012-10-03 10:54:34] VERBOSE[11631] manager.c: == Manager 'Admin' logged on from 192.168.11.3 [2012-10-03 10:54:34] VERBOSE[11632] pbx.c: -- Executing [1811@inside-leg:1] SIPAddHeader("Local/1811@inside-leg-6afa;2", "Call-Info:<sip:>;answer-after=0") in new stack [2012-10-03 10:54:34] VERBOSE[11632] pbx.c: -- Executing [1811@inside-leg:2] Dial("Local/1811@inside-leg-6afa;2", "SIP/1811,20") in new stack [2012-10-03 10:54:34] ERROR[11632] astobj2.c: refcount -1 on object 0xacc24608 [2012-10-03 10:54:34] ERROR[11632] astobj2.c: refcount -2 on object 0xacc24608 [2012-10-03 10:54:34] ERROR[11632] astobj2.c: refcount -3 on object 0xacc24608 After the last refcount error the log ends, and asterisk core dumps. | ||

By: Matt Jordan (mjordan) 2012-10-19 11:04:23.894-0500 What was the result of your testing? By: Andrew Parisio (parisioa) 2012-10-19 12:14:37.765-0500 No segfaults, but i had a very interesting lock up, i had to kill 9 it, i forgot to get a core show locks. I'm waiting to see if it will happen again. I haven't had a lock up like that in years. By: Matt Jordan (mjordan) 2012-10-19 12:46:20.307-0500 If you can reproduce it lets go ahead and file that as another issue. Repurposing issues in JIRA gets confusing very quickly :-) I'm going to go ahead and close this out as a duplicate of ASTERISK-20119 - if it turns out not to be the case, please let me know (or another bug marshal in #asterisk-bugs or the asterisk-bugs mailing list) and we'll reopen it.
