Yes we do... and we have many cases with support for issues with the bdbreconfig. For more info, you might just search at the support site on the cases logged for Reger-5.2 Version. Its a lot improved/enhanced and stable for now, but we still face issues ocassionally, due to developers making the table/domain/index changes or with the binary itself. We are now so proactive that we take a hot backup of OS and database before code migrations and if anything fails we can restore the whole environment in few hours without badly exceeding our sunday downtime period. This has been one of our proactive monitoring tools.
