Summary:                    Asterisk crashes randomly with a segmentation fault
in  __res_vinit ()
Description: 
I am having Asterisk crash randomly many times during the day. Asterisk is
just acting as a registrar for around 30 SIP peers.

These phones makes a SIP call to Asterisk which does a B2B call to another
piece of hardware.

I'm running safe_asterisk and getting 'Asterisk died' emails randomly
throughout the day. For example, yesterday I had 4 crashes (10.36, 10.41,
12.58, 19.50).

My core dumps are always the same...

I'm not really a developer but I hope this information is useful.

There isn't much we can do here, since the crash it outside of our code
(inside of glibc).  I would recommend upgrading your system.
