| Comments: | By: Filip Frank (frenk77) 2012-04-23 05:45:27.456-0500 I maybe found this problem too, after our DNS failure. All phones was unregistred. It send SIP register but asterisk not sending response him. By: Nikola Ciprich (nikola.ciprich) 2012-04-24 03:06:46.404-0500 Anyone? Is there something I could do to help debugging this issue? It seems to be quite serious.. By: Matt Jordan (mjordan) 2012-04-24 12:40:57.766-0500 Please attach debug output, be it log statements or the output of 'core show locks', as a file and not in the issue description. By: Nikola Ciprich (nikola.ciprich) 2012-06-30 01:25:25.432-0500 so the problem seems to be present in 1.8.13.0 as well.. we've had multiple such hangs on one of our customer's boxes. What I noted is, that they had multiple BLF buttons set to nonexistent extensions... I wonder whether this is related? By: Kien Kennedy (kiennd) 2012-10-18 01:58:40.729-0500 I had same problem, too. I have tried many version of asterisk (1.8.11, 1.8.15 and the newest 1.8.18-rc1) but the problem is still occured. The system was worked well in 1-2 months, but recently, it has these problems. By: Nikola Ciprich (nikola.ciprich) 2012-10-18 02:07:19.184-0500 our testing 1.8.17.0 just hung few minutes ago, so yes, the problem is definitely still present. By: Kien Kennedy (kiennd) 2012-10-18 04:25:19.112-0500 Any one try older versions? 1.4 or 1.6, more stable ? By: Matt Jordan (mjordan) 2013-04-19 10:56:34.145-0500 There is a patch on ASTERISK-21389 that should prevent res_timing_pthread from blocking callers. That should resolve this issue. If you test with that patch and this issue is still a problem, please let a bug marshal know in #asterisk-bugs and we will be happy to reopen this issue. Thanks! | ||||
