Summary:                    Asterisk crashes with a segmentation fault in
timing.c   [ast_timer_ack]
Description: 
This issue has happened twice, both backtrace.txt files are attached. 

Possible Clue: So far this issue only happens about 10 - 11 hours after we
restart asterisk or stop and start asterisk.   Two days in a row, we would
restart asterisk at mid-night then between 10:00 am to 11:00 am we would
get the error that crashes Asterisk.  If we don't restart asterisk we can
go days without a crash.

FYI - other crashes we have had over the last two weeks are issues,
0017686 and 0017687.

Really?

Per your backtrace:

https://issues.asterisk.org/view.php?id=4  0x00a65a7e in do_timing (arg=0x0) at
res_timing_pthread.c:468

Per the 1.6.2.10 ChangeLog:

2010-07-22  Leif Madsen <lmadsen at digium.com>

	* Release Asterisk 1.6.2.10

	* Included a fix for res_timing_pthread per the description below:

	  r278465 | russell | 2010-07-21 11:15:00 -0500 (Wed, 21 Jul 2010) | 41
lines

	  Use poll() instead of select() in res_timing_pthread to avoid stack
corruption.
	  This code did not properly check FD_SETSIZE to ensure that it did not
try to
	  select() on fds that were too large.  Switching to poll() removes the
limitation
	  on the maximum fd value.
