HI!
Playing with recent RE24 and MIT Kerberos' LDAP backend I noticed this
in syslog:

Oct 11 10:15:35 nb2 slapd[3888]: =>  bdb_dn2id_add 0x8d: put failed:
DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock -30995
Oct 11 10:15:35 nb2 slapd[3888]: =>  bdb_dn2id_add 0x8c: put failed:
DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock -30995
Oct 11 10:15:35 nb2 slapd[3888]: conn=5 fd=29 closed
Oct 11 10:15:35 nb2 slapd[3888]: =>  bdb_dn2id_add 0x8d: put failed:
DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock -30995

Can't reproduce though. Under which circumstances can this happen?

Various multiple access scenarios. It's not an error, that's normal in a 
transactional environment. The operations are automatically retried, ignore 
these messages.
