Summary:                    libc6/malloc/free abort of asterisk
Description: 
I am not definitly sure on how to describe this crash, as, obviosly it is
not really a crash as it's not a segfault so much than a controlled abort,
as you can see in the backtrace.

As it has something to do with music_on_hold (as seen in the backtrace) it
may be associated with bug https://issues.asterisk.org/view.php?id=15195

The /etc/asterisk/musiconhold.conf is:

[default]
mode=files
directory=/var/lib/asterisk/moh


the /var/lib/asterisk/moh contains this files:
-rw-r--r--  1 asterisk asterisk    0 2009-07-30 21:12
.asterisk-moh-freeplay-wav
-rw-r--r--  1 root     root        0 2009-04-01 18:28

LICENSE-asterisk-moh-freeplay-wav

whatever the .asterisk-moh-freeplay-wav is.

No information in the full-log, to be fair we have high logging not
activated in production as it drains IO and ressources. As it is not a
segfault there are no Logs in kern.log or syslog



If you need any more information please tell and i'l be happy to provide.

Bug 15109 was opened and determined to be a memory abort when using moh
files based mode. I have done lots of work to try and reproduce under
Valgrind but Asterisk will not crash under Valgrind in this scenario.

I recommend you follow these instructions and try tilghman's Asterisk
patch to capture memory issues without having to run Asterisk under
Valgrind.

I hope you can attempt this soon because it will be at least a week until
I will have an opportunity to try tilghman's work on malloc_hold and get
this problem fixed.  This issue is blocking the release of 1.4.27 and
preventing me from upgrading a few mission critical sites.
