I would put these back to whatever is most appropriate to your
environment. I see no reason (yet) to introduce more variables into the
situation.

It sounds like you're using bdb or hdb. I'm guessing that the automatic
database recovery isn't, well, automatically recovering. You can try
running slapd -d -1 at the command line to see if this is the case. It
should be fairly obvious where it hangs; probably somewhere near a message
about bdb_db_open() or "attempting recovery" or such.

I might try stopping slapd and running db_recover by hand. (I'm not sure
if that should make a difference, but it shouldn't hurt.) If that doesn't
seem to work, you can also try "catastrophic" recovery. See the Sleepycat
documentation for details about the command.
