Change free() to abort() instead of printing a message when it gets this
error, and examine the coredump.  Go from there.

You can do this by
% export MALLOC_OPTIONS=A
before running inetd.

% ln -s A /etc/malloc.conf
will do the same for all programs.  (If I understood the man-page correct,
that is.  Using the 'contents' of a symbolic link seems weird.)
