Summary:                    Random crashes
Description: 
Asterisk randomly crashes on me
I'm running Ubuntu Server and have tried asterisk 1.6.1.17 and 1.6.1.18

Asterisk randomly crashes, my first bt's pointed at 
https://issues.asterisk.org/view.php?id=0  0xb7f6d410 in __kernel_vsyscall ()

__ast_pthread_mutex_unlock (filename=0x2449 <Address
0x2449 out of bounds>, lineno=-1239132680, func=0x1 <Address 0x1 out of
bounds>,
    mutex_name=0x0, t=0xb62455f0) at
/usr/src/asterisk-1.6.1.18/include/asterisk/lock.h:731

But that is because of the stack protector, so i recompiled asterisk
without optimize and disabled the stack protector to generate the attached
backtrace

The information for how to use valgrind is available in doc/backtrace.txt
of your Asterisk source. Since switching away from res_timing_pthread seems
to have resolved your issue, unless you are able to reproduce the problem
and provide the valgrind information there isn't much point in leaving this
issue open.

I'm going to close this issue for now, but if you are able to provide the
information please reopen this issue. Thanks!
