Quanah, These are the settings i have in slapd.conf grep cach /etc/openldap/slapd.conf cachesize 100000 idlcachesize 300000 dbconfig set_cachesize 0 2097152 0
So how many total entries are in your database? You still haven't answered that.
Also, your dbconfig set_cachesize parameter is disturbingly low. You should delete it to ensure the value in your DB_CONFIG file (8 0 1 remains honored).
