Please add a checkpoint setting to the database section of your
slapd.conf for this bdb database.
(I suspect what is happening is that you are reaching 2GB of active
transaction log files, which seems to cause problems ...).
Also, it seems you have some transaction log files created when using an
earlier version of Berkeley DB, you should at least run db_checkpoint
before chanding Berkeley DB versions (which should flush the
transactions to the database so you can remove the transaction log file).
