I am not sure if this is your problem but have you tried running the bdb utilities to recover from a corrupted database. I believe the command is db_recover. We have had to do this a few times in the past.

It's clear from his error log that such actions will be useless. His transaction log is clearly missing a large amount of data. The BDB transaction support can't help you if your hardware fails to preserve the transaction log data.
Hello ,
I did db_recover in the bdb database directory and I am able to start slapd, but may be the data as you said, would have been last. I will check that.. Thanks
Arunachalam.

If we are sure that transaction logs are persisted by making the bdb flags DB_TXN_SYNC, then there will not be problem if hardware fails and restarts right?
