Every so often asterisk crashes and then restarts. I am not seeing any core dumps on the box. The only I thing I see every time is a second before Asterisk crashes there is a AAAA lookup for the boxes hostname. As soon as it gets the response I see that asterisk is restarting. Any idea what would cause this and how would get a dump or further debug? I did build Asterisk with DONT_OPTIMIZE and BETTER_BACKTRACES but not seeing any traces anywhere.
