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...

Reading symbols from /lib/libgcc_s.so.1...done.

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

Just been checking the asterisk log... it would appear I get a bunch of SIP warnings before the crash:

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.
