| Description: | Sometimes (we could not find a trend) asterisk just stops responding to sip registration requests. At the same time it responds to console commands (e.g. sip show channels outputs channels which was active at the freeze moment) excepts "sip reload", which does not work. This happens two or three times a day, it isn't good for our call center. Which information should we provide? (full log with enabled sip debug, verbose 4, and debug 4 have size about 800 MiB) | ||

By: Leif Madsen (lmadsen) 2011-07-11 14:51:32.749-0500 Debugging deadlocks: Please select DEBUG_THREADS and DONT_OPTIMIZE in the Compiler Flags section of menuselect. Recompile and install Asterisk (i.e. make install). This will then give you the console command "core show locks." When the symptoms of the deadlock present themselves again, please provide output of the deadlock via: # asterisk -rx "core show locks" | tee /tmp/core-show-locks.txt # gdb -se "asterisk" <pid of asterisk> | tee /tmp/backtrace.txt gdb> bt gdb> bt full gdb> thread apply all bt Then attach the core-show-locks.txt and backtrace.txt files to this issue. Thanks! Looks like a deadlock, in which case you'll need to provide a backtrace from the running process along with 'core show locks' data.
