Description:When the channel is redirect on this exten:

exten => _X.,9,Park(6000000,someContext,${EXTEN},2,s)

( with the option 's' for silence the message)

sometimes asterisk Crashes.

This is the Back Trace of the core dump:

This happens very frequently. For understanding the impact of the problem, the crash happens 4 time per week on a server that processes almost 140000 call at day, and the Asterisk task is always on (server never restarts).
I hope that this BT is enough to understand the cause of the problem.

We'll need a full backtrace.


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!
