So if it's not obvious, we're working on migrating our openldap deployment to mdb from hdb :), I apologize for the flurry of questions, this will be the last, at least for today ;).
I'm trying to evaluate the optimal configuration for mdb; it seems like for the most part you can just set maxsize and move on if you don't have performance issues, but one flag I've seen frequently mentioned for improving performance is writemap. This seems like a win all around, unless there is some bug that results in erroneous writes into the mapped region, in which case it could potentially cause major database corruption. For those that have been running mdb in the field for a while, are you using writemap? Have you ever run into any corruption because of it?
I use writemap and nometasync. I've never encountered corruption because of using writemap.
