There is no version 3.0 (AFAIK); current version is 2.3.

An objectClass cannot have 6000 entries; the objectClass is an attribute
of each entry.  Of course, 6000 entries can have the same objectClass.
Is this what you mean?  I suggest you try to explain your problem mking
sure you use appropriate terms, especially when they have a clearly
defined meaning in the X500/LDAP data model.

Sounds like you're using the LDBM backend, and hitting the giant lock
issue.  If this is the case, then it's working as intended.  I'd note
that it's unlikely you can use the LDBM with OpenLDAP 3.0 (if there'll
ever be one) because LDBM is deprecated since OpenLDAP 2.2, I believe,
and will disappear from OpenLDAP with version 2.4.

Use back-bdb or back-hdb, if you're using back-ldbm; otherwise clarify
your problem.  Since up to now you didn't bring any evidence of a bug in
OpenLDAP software, I suggest we continue this discussion on the
openldap-software mailing list.  This ITS will be closed.
