Infrastructure

Robert:
when upgrading a component, slapd takes more than a few seconds to die, do not kill it. For some reason, slapd sometimes takes 10-20 minutes to perform its shutdown procedure. If slapd is killed before completing the process there appears to be a slight chance that the underlying datastructures become corrupted.

Matt:
I've read that slapd shutdowns are slow when they are not checkpointed enough relative to the memory available to them. You might consider increasing the memory or increasing the minimum checkpoint interval.
