Create an MDB database with approximately 130,000 entries.

Delete the entries sequentially.  Deletes will sporadically fail in blocks:

deleting entry "uid=testuser44968,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"

deleting entry "uid=testuser44969,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"
ldap_delete: Other (e.g., implementation specific) error (80)
        additional info: entry index delete failed

deleting entry "uid=testuser44970,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"
ldap_delete: Other (e.g., implementation specific) error (80)
        additional info: entry index delete failed

...

continues to fail up to:


deleting entry "uid=testuser45093,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"
ldap_delete: Other (e.g., implementation specific) error (80)
        additional info: entry index delete failed

deleting entry "uid=testuser45094,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"
ldap_delete: Other (e.g., implementation specific) error (80)
        additional info: entry index delete failed

deleting entry "uid=testuser45095,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"
ldap_delete: Other (e.g., implementation specific) error (80)
        additional info: entry index delete failed

deleting entry "uid=testuser45096,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"

deleting entry "uid=testuser45097,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"

deleting entry "uid=testuser45098,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"

deleting entry "uid=testuser45099,ou=people,dc=zre-ldap004,dc=eng,dc=vmware,dc=com"


then deletes work for a while again, then fail again for a while, etc.
