I was very careful to manually db_recover prior to start. "BEFORE" was while slapd was running. I then:
# pgrep slapd 15889 # pkill -INT slapd [watched for] slapd[15889]: [ID 707592 local4.debug] slapd shutdown: waiting for 0 operations/tasks to finish [then the process went away, although I'm more than a bit confused by no "slapd stopped" -- does that not syslog?]
and then I generated the "AFTER" run.
