openLDAP BDB back-end trouble

[David Schell <dschell@disisit.com>]

We have been using openLDAP with a BDB backend using Fedora Core 4  
for about a year.  Unfortunately, we periodically experience a  
problem with BDB database corruption preventing openLDAP from  
starting if the server is shut down hard (such as during an extended  
power outage).

While I have gotten quite good at restoring the database from a  
nightly backup, I was wondering if there were database back-ends that  
would better handle these situations?
