RE: what is the most stable platform to run openldap on?
I did not setup any additional indexes because all lookups are exact dn searches. Would ITS#1812 still apply in this case? Yeah I know it is probably wishful thinking :-)

See ITS#2812 for
a workaround. If you really want a rock-stable system no matter what, go back
to a uniprocessor machine.
By the way, BDB 4.2.51 should be out in a couple days, with fixes that make
it compatible with OpenLDAP 2.1. It may be worth trying that as well.
