Does this happen only with client activity, or does it also happen when the
server is dormant?  If the server is being actively used by clients, what's
the rate of connects/disconnects?

Can you post your slapd.conf for the system in question?

Finally, if we're leaking memory, it would probably be helpful if you could
run slapd under valgrind for a short time so that we can see where the leak
is happening.
