That is very curious and it does not seem to be the behaviour that
I get when using the most recent version:

As ldirectord is a self-contained text file, would it be possible for you
to post either the file itself or a diff between it and the version at the
URL above?

Please CC me (so if the list blocks the post for being too big at least
I'll be able to see it).

On the subject of a full restart. Ldirectord really ought to have
a method of being restarted without taking down all the services when
it gracefully exits. But for now it doesn't.

In a pinch you might be able to do the following,
but please test it first:

kill -9 <pid of ldirectord>  # ldirectord won't have a chance to clean-up
/etc/init.d/ldirectord start # ldirectord won't clean-up on start, thats ok
