I know this is probably a "don't do that", but I was somewhat surprised by the outcome.
I was doing a: slapadd -S 1 -q -w -l ~/load_noCSN.ldif
... and wanted to see what was actually added to the database, so I ran slapcat - which immediately made bot apps crash.
=> bdb_last_id: get failed: DB_PAGE_NOTFOUND: Requested page not found (-30986)
(slapd 2.4.19, BDB4.8 using hdb)
