I can give you a complete image where just changing kernel (everything is same, of course) corruptions goes away. we spent a lot, I mean a *lot*, of time looking for our code mistake, and so on. I don't want to seem rude, but I am sure that Berkeley DB corruption we have seen (not just Klibido, but I also think about postgrey, and so on) depends on this bug. I repeat, if you have time/interest I can give you a complete machine to see the problem.
