Ghosting Data

I was wondering if anyone has seen anything like this before:

root# ldapsearch [blah] 'cn=username' dn cn

# extended LDIF # # LDAPv3 # base <ou=people,o=base> with scope subtree # filter: cn=username # requesting: dn cn #

# username, people, base dn: cn=username,ou=people,o=base cn: username

# username, people, base dn: cn=username,ou=people,o=base cn: username

# username, people, base dn: cn=username,ou=people,o=base cn: username

# username, people, base dn: cn=username,ou=people,o=base cn: username

# search result search: 2 result: 0 Success

# numResponses: 5 # numEntries: 4

Then when I try to delete the entry:

root # ldapdelete Enter LDAP Password: cn=username,ou=people,o=base ldap_delete: No such object (32) matched DN: ou=people,o=base

I haven't tried doing restarting slapd or the usual db_recover stuff yet as it's not causing a problem (yet). Is it symptomatic of a known issue?

slapd 2.3.30 back-hdb Built against db 4.2.52 (standard Ubuntu Edgy package)
