Summary:                    Asterisk freezes when reloading dialplan
Description: 
Hi,

I had this occurs twice in the last 3 days.  When doing 2 "dialplan
reload", asterisk just freezes.  It doesn't crash (and therefore doesn't
restart). It just stays there until I rstart it manually, and it doesn't
process calls or SIP registrations.

This sounds like a deadlock to me. Please follow the instructions below. It
might be also useful to provide a backtrace of the running process when
this happens.

~~~~~~~~~~~~~~~~~~~

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!


~~~~~~~~~~~~~~


Thank you for your bug report. In order to move your issue forward, we
require a backtrace from the core file produced after the crash. Please see
the doc/backtrace.txt file in your Asterisk source directory.

Also, be sure you have DONT_OPTIMIZE enabled in menuselect within the
Compiler Flags section, then:

make install

after enabling, reproduce the crash, and then execute the instructions in
doc/backtrace.txt.

When complete, attach that file to this issue report. Thanks!
