Good idea (about not doing a "me too".) I was just suggesting looking for
a match before creating a new ticket.

Make sure you've done the ulimit -c unlimited. Not having done that
can prevent cores. Also, there may be other things that change the
location of the cores.

See the kernel.core_pattern = /tmp/core.%t.%u.%p.%e example. Look in
/etc/sysctl.conf and/or /etc/sysctl.d/* for core related issues.

I recall that Mythbuntu sets some of these things on-the-fly at boot
time. Your distro may too. Try this to see your current settings:

     sysctl -a 2>&1 | grep kernel.core
