openldap openldap-2.0.25 using 700M of RAM

Hello list,

I have an openldap server (2.0.25) on a redhat linux box (kernel 2.4.18-4smp) with 2 gigs of ram serving an ldap directory with about 4000 records. The directory has a considerable amount of load because a mail server is matching email addresses against it.

Anyway, the ldap processes are collectively using 740MB of RAM on the system as shown by the process list below.

Is this memory usage normal?  Why does open ldap use so much memory?

Here is the ps:

Here is some kernel info:

Here is part of my slapd.conf:
