| Description: | I get random deadlocks (3-4 times in a week). See attached Backtrace! - Asterisk SVN-branch-1.6.2-r296466 (from 27.11.2010) - Compiled with "Debug Threads/Locks" and "Don't optimize" | ||||
| Comments: | By: Tilghman Lesher (tilghman) 2010-12-18 13:54:35.000-0600 Please also enable BETTER_BACKTRACES (found when using ./configure --enable-dev-mode) and get a new 'core show locks'. By: Tan Tuerel (thsgmbh) 2010-12-19 06:03:38.000-0600 Can't set BETTER_BACKTRACES because of missing dependencies!? I have installed latest "binutils-devel and zlib-devel"... (Linux 2.6.18-194.26.1.el5 #1 SMP x86_64 x86_64 x86_64 GNU/Linux) -------- In "configure.log" I get many "undefined references" errors: configure:15664: gcc -o conftest -g -O2 conftest.c -lbfd -lm >&5 /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libbfd.a(opncls.o): In function `bfd_fill_in_gnu_debuglink_section': (.text+0x194): undefined reference to `lbasename' /usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libbfd.a(opncls.o): In function `bfd_create_gnu_debuglink_section': (.text+0x289): undefined reference to `lbasename' ... --------- find / -name libbfd*.* /usr/lib64/libbfd-2.17.50.0.6-14.el5.so /usr/lib64/libbfd.a Any idea??? By: Tan Tuerel (thsgmbh) 2010-12-20 09:22:58.000-0600 Next deadlock (with latest SVN Version). Asterisk SVN Version from 19.12.2010 (r298962) !!! Backtrace attached... (still without "BETTER_BACKTRACE" option) By: Tan Tuerel (thsgmbh) 2010-12-22 10:12:46.000-0600 Another deadlock... :-( very annoying !!! Backtrace attached... By: Tan Tuerel (thsgmbh) 2011-01-12 09:29:27.000-0600 Still permanent deadlocks in SVN 1.6.2 Revision 300165: See attached backtraces: 06.01.11 ---> Locked Here: channel.c line 2163 (ast_waitfor_nandfds) 12.01.11 ---> Locked Here: channel.c line 2163 (ast_waitfor_nandfds) By: Jeffrey C. Ollie (jcollie) 2011-01-27 14:13:09.000-0600 Regarding the 'lbasename' undefined reference, I believe that you need to add "-liberty" to the list of libraries. By: Tilghman Lesher (tilghman) 2011-01-27 14:54:59.000-0600 jcollie: patch uploaded to fix that error (only set when necessary). By: Tan Tuerel (thsgmbh) 2011-01-27 15:21:15.000-0600 Thank you for the patch but I just compiled asterisk with: ./configure --enable-dev-mode LIBS=" -liberty" make menuconfig (DONT_OPTIMIZE, ENABLE_BETTER_BACKTRACE,...) make BFD_LIB=" -lbfd -liberty" without compiler errors... I will give it a try... By: Tan Tuerel (thsgmbh) 2011-02-03 02:44:33.000-0600 Another deadlock/freeze... (see attached file) Now with "BETTER_BACKTRACES" enabled !!! In nearly EVERY backtrace you can find the function "find_call" (notifycid?) and "handle_statechange" (BLF?) !??! By: Matt Jordan (mjordan) 2013-04-08 15:46:39.608-0500 This appears to duplicate ASTERISK-17387. If you are still experiencing this problem on a recent version of Asterisk 1.8, please contact a bug marshal in #asterisk-bugs and we'll reopen this issue. Thanks! | ||||
