Comments: | By: Leif Madsen (lmadsen) 2010-02-10 15:17:40.000-0600 Please provide a console trace with 'core set debug 10' and 'core set verbose 10' with debug level logging enabled via logger.conf. Also provide a proper backtrace per the doc/backtrace.txt documentation within your Asterisk source.

() By: Marco Loewl (marco_wc) 2010-03-15 13:30:19 i have tested with more descriptors, but i think they are lost. I will test agin this week ... By: Paul Belanger (pabelanger) 2010-04-28 15:58:56 Ping! Any update on this? Cleaning up the issue tracker. By: Marco Loewl (marco_wc) 2010-04-29 00:51:40 sorry, i'm in the release stress :-( but the trace what i have send you is make with higher descriptors (ulimit -n) this solved not the problem ! By: David Woolley (davidw) 2010-04-29 02:10:29 No-one seems to have noticed the most serious error message here: *** glibc detected *** asterisk: munmap_chunk(): invalid pointer: 0x0894ca08 *** Looks like there is memory corruption. With the caveat that it can sometimes make the system run too slowly even to do the test, I believe the debugging protocol requires the use of the procedure in doc/valgrind.txt, at this point. (The abort, rather than segmentation fault, in the last backtrace, also tells you that you are dealing with some sort of memory management problem By: Leif Madsen (lmadsen) 2010-04-30 13:48:17 Thanks for the information davidw! marco_wc: per davidw, you will need to follow the instructions in doc/valgrind.txt in order to move this issue forward. By: Paul Belanger (pabelanger) 2010-06-01 13:21:25 Suspended due to lack of activity. Please request a bug marshal in #asterisk-bugs on the IRC network irc.freenode.net to reopen the issue should you have the additional information requested. Further information can be found at http://www.asterisk.org/developers/bug-guidelines By: Marco Loewl (marco_wc) 2010-06-07 03:46:29 sorry, why do close this :-( i will send you next week after my release the new information ! sorry, but this is not OK ! all version from 1.6.x is very unstable :-( By: Leif Madsen (lmadsen) 2010-06-09 10:20:27 I notice you're using res_timing_pthread -- please try using something like res_timing_dahdi instead and see if that helps. For some reason res_timing_pthread is not very stable right now. Additional debug information while using res_timing_pthread would be greatly appreciated. This includes valgrind output along with a backtrace while DONT_OPTIMIZE has been selected (and subsequently compiled) in menuselect. Please attach the results of that information to this issue.
