I had a similar problem which went away when after I went through all my perl
scripts that used perl-ldap and made sure that they properly closed their
connections to the LDAP server before they ended. Once I stopped leaving stray
connections to the server all over the place, things got *much* better, and I
haven't seen a problem since.

The Greatest tragedy in mankind's entire history may be the
hijacking of morality by religion. However valuable -- even
necessary -- that may have been in enforcing good behavior on
primitive peoples, their association is now counterproductive.
Yet at the very moment when they should be decoupled,
sanctimonious nitwits are calling for a return to morals based
on superstition.
