In general slapd writes to disk as soon as possible, depending on
pending read operations, that is, a delay of a few seconds my
occur. Not writing to disk for a few month seems to be quite odd.If
you use a bdb or hdb database you might try to recover the database
by means of db_recover.
In order to force slapd to write to disk you may define a checkpoint in
IIRC, it only flushes to disk when told to, which is either via the
checkpoint settings, or a *normal* slapd shutdown. Otherwise, it does not.
So his scenario makes perfect sense to me. Assuming the cache setting
holds the entire DB, I believe.
