Seriously? This is really ancient release almost 10 years old.
Being in your position my next task would be to update such an old
system (not only because of OpenLDAP).

I am, unfortunately it will be a Windows Server.

Logging region out of memory; you may need to increase its size
db_open(/var/lib/ldap/id2entry.bdb) failed: Cannot allocate memory (12).

What does your monitoring say about memory usage before that log message?

System-wide memory usage is irrelevant, this is a BDB error message.

Memory usage was fine in TOP. The tweaks fixed it, which is just what I needed to get it going for a short time.

See https://docs.oracle.com/database/bdb181/html/api_reference/C/envset_lg_bsize.html

And switch to back-mdb after you upgrade to a current OpenLDAP release.

Actually, I am moving to Windows 2016. :( Not because of me, but I plan on retiring in a few years and when I do, whoever comes after me will more than likely be a Windows guy and not Linux. I am trying to get everything ready for the next person when I leave. We live in a small Rural Community and there are virtually no techs around here that deal with Linux anymore.

Thanks for the help.
