Here's your problem.  We do not support res_perl.so, as it is frequently a source of crashes.

I don't use res_perl.so . I think that shouldn't be the problem .

Okay, then I need a 'bt' and a 'bt full' on this backtrace.

Attach files with the required data ( 'bt' and 'bt full' ).

It seems a memory problem, but the server has ECC memory with error correction and we have a monitoring tool that notifies us by email if this happens.

You may want to recompile with DONT_OPTIMIZE - most of the values have been optimized out

I also need the WHOLE output of 'bt full', not just the first frame.

Hi all,

The problem of asterisk crashing persist after the voicemail is executed.
After the crash, 2 files are generated in /tmp/:
astmail-nGgzOj (with 0 bytes)
core.3366

Please, find attached the full output of the core dump file.

It's shown the gdb output following the voip-info.org steps:
http://www.voip-info.org/wiki-Asterisk+debugging

tracing a core dump file in /tmp
  1. start Asterisk with safe_asterisk
  2. enter "gdb asterisk core.xxxx"
  3. enter "bt" while in gdb (or do a "bt full")
  4. enter "thread apply all bt"

Thanks in advance

As ZX81 correctly noted, you'll need to recompile with DONT_OPTIMIZE so that stack values aren't removed for optimization.
