Running a bdb backend and sync replication, I was getting a core dump on the consumer whenever there was a modify or delete on the producer (though NOT on add). I traced it to the lack of a "searchbase" entry in the consumer's slapd.conf - adding searchbase="" seems to have fixed the problem. (Happened with db 2.2.52.4)
