Sorry, could you explain this a little more?

I wasn't aware that LDBM was susceptible to the same inconsistencies
as BDB.  I thought the lack of transactions/checkpointing prevented
this.  And if this situation did occur, I thought 2.3 was smart enough
to try fixing itself.

I did see some evidence of corruption, but I thought it was due to a
problem with db_upgrade, or a misconfiguration.  Nevertheless, I will
try a db_recover.
