That's sudo setting a coredump limit to prevent you from getting
any security related data from a coredump. sudo compiled with
SUDO_DEVEL will have this disabled and lets you debug sudo.

That's probably uid 73 not having write permission in the current
directory. You can set the corename property of a process or
the defcorename with sysctl to redirect coredumps to a different
place, see sysctl(8) for details.
