Quanah,

thank you for your warning.

We are aware that it is a very old release and a version upgrade is already being planned.

But for the moment, that is the currently installed version and that is what produced the strange phenomenon.

I would note you're talking about OpenLDAP and LMDB releases that are over
4 years old, past which point numerous issues have been fixed for both.

LMDB 0.9.15 Release (2015/06/19)
OpenLDAP 2.4.41 Release (2015/06/21)
