Those fixes would not address this problem. The fact that the BDB
library is complaining about a version mismatch means the system is

You may with to upgrade to 2.3.13, where there were fixes to
autorecovery since 2.3.11.
Much as I agree that upgrading to the most recent source is a good idea,
it is *not* a good idea to blindly encourage people to upgrade when
there is no basis for believing it will in any way address the problem.
Get a real diagnosis first; never suggest a course of action before you
understand the actual problem.
It's clear from the log that this particular slapd binary is linked with
a BDB 4.3 library. The problem seems to be that a BDB tool from a
different version was used to access the database at some point. This
implies that the operating system is misconfigured; either the PATH or
the LD_LIBRARY_PATH are pointing to the wrong place, or some other
similar mistake. No amount of OpenLDAP software patching can correct
such a sysadmin mistake.
