Matt,
Does it refuse to crash dump or is it that you can't get the core file back?
Make sure you have enough disk space in /var/crash for capturing the
dump. You need at least as much free disk as you have memory configured.
There was a post saying that fsck may be trashing core files if it
starts using swap. To maximize the chances of recovering the core file
boot into single user after the crash and do the following:
fsck -y # or fsck and read every question, if you're paranoid
mount -f / # remounts root read/write
mount /var
savecore /var/crash
exit
