----------------------------------------------------------------------
Additional information is required:
* a backtrace is probably useful
* additional information about deadlocks and such might also be useful
Also, can you reproduce this without chan_capi? We can't support
third-party tools here.
----
We require a complete debug log to help triage the issue.
This document will provide instructions on how to collect debugging logs
from an Asterisk machine for the purpose of helping bug marshals
troubleshoot an issue:
http://svn.digium.com/svn/asterisk/trunk/doc/HOWTO_collect_debug_information.txt
----
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!
