OpenLDAP 2.3 has not been supported for several years.  Since it stopped 
development, there have been hundreds, if not over a thousand, bug fixes 
and improvements.  Furthermore, I'm going to guess that you are running 
RH's build of OpenLDAP 2.3, which was even further behind than the last 
release of OpenLDAP 2.3.  Given the information you provided, I would guess 
that there is some bug in the version of BDB that OpenLDAP was linked to 
that caused the error.  I would note that at one point RH was linking 
OpenLDAP against BDB version 4.3, despite the fact OpenLDAP's configure 
script explicitly disabled such linking because BDB 4.3 was known to have 
serious issues.  If your 2.3 OpenLDAP is linked to BDB 4.3 that could well 
be the cause of your issue.

Beyond that, trying to investigate any further is a waste of everyone's 
time.  Upgrade to a modern supported version of OpenLDAP, and build your 
own packages, don't rely on distribution packages.
