Hello Howard,
I have had the same errors with openldap 2.2.12 and 300Mb of DB Cache for another 8 hour test and 200Vusers. With a 4cpu-4Gb Ram machine i don't see why the hell can't it manage itself well in memory.
It's really un-acceptable results and i guess we have a really long way to go in making openldap scale.
That's really quite a broad statement.
