I would note that the current release of OpenLDAP is 2.4.35.  I would note 
that OpenLDAP 2.4.23 is nearly 3 years old.  I would note that numerous 
significant fixes to MMR and syncrepl have been made to OpenLDAP since 
2.4.23.  I would note that the version of OpenLDAP 2.4.23 shipped by Redhat 
is known to have various issues.  I would give my usual advice of using a 
current OpenLDAP release.  If you are unable to build it yourself, you may 
wish to use the packages from the LTB project:

<http://ltb-project.org/wiki/download#openldap>

Or to put it more succinctly:  You are expected to have issues with the 
2.4.23 version, even if it may take some time to encounter them.  If you 
truly want help resolving issues with the 2.4.23 build as provided by 
Redhat, then the proper support channel for their packages is to contact 
Redhat and to ask them to fix the version they have released to their 
customers.  Otherwise, use a current build of OpenLDAP on your servers.

Hope that helps!
