I'm running linux, but I'll look and see what the limits are. However, it
seems to me that I've got a lot more established connections than I can
explain by the stuff that calls LDAP, so I'd rather clean up the calls than
increase the limits.
I guess I'd better go through my own code and make sure that I'm properly
unbinding from ldap.

Are you willing to share the script? I've been using perl-ldap-0.24, but I
can either also install PerlLDAP or modify it to use perl-ldap.

I run squid, but not on any of the boxes that his has happened on, and the
boxes that have Squid aren't doing ldap calls.

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.
