The messages that get dumped to the kernel log aren't of much use.  See
below for more info.

That *should* be a good combination.

If you still have the coredump files, you can use the ast_coredumper
utility located in /var/lib/asterisk/scripts to extract the human-readable
stack traces.  "sudo /var/lib/asterisk/scripts/ast_coredumper --help" will
get you more info on how to run the command.  The *-thread1.txt file it
produces will be the most helpful but all 4 should be attached to the
Asterisk issue should you decide to create one.
