syncrepl missing deletion records?

[Jorgen Lundman <lundman@lundman.net>]

Hello list;

db-4.8.30.NC
openldap-2.4.23

We have on a few occasions come across a syncrepl problem where some deletion 
records do not happen everywhere. Today I was looking at two such problems;
Usually the procedure is to delete the old record, then add a new record.

#1: deletion of A records in ou=dns
    ldapmaster has it deleted.
    ldapslave03 has it deleted.        (syncrepl with ldapmaster)
    dns02, dns04 has it deleted.       (syncrepl with ldapslave03)
    dns01, dns03 still has the record. (syncrepl with ldapslave03)

In detail, from dns03.unix, which now has two records:

dn: DNSRecord=A1,DNSHostName=@,DNSZoneName=customer.com,ou=dns,dc=work
objectClass: DNSARecord
DNSRecord: A1
DNSHostName: @
DNSType: A
DNSIPAddr: zz.yy.xx.ww (new IP in reverse)
DNSTTL: 600
structuralObjectClass: DNSARecord
entryCSN: 20101021232823.000000Z#000002#000#000000
entryUUID: a43076ee-71b6-102f-95dd-c33ccbc720c3
creatorsName: cn=admin,dc=work
createTimestamp: 20101021232823Z
modifiersName: cn=admin,dc=work
modifyTimestamp: 20101021232823Z

dn: DNSRecord=A,DNSHostName=@,DNSZoneName=customer.com,ou=dns,dc=work
objectClass: DNSARecord
DNSRecord: A
DNSHostName: @
DNSType: A
DNSIPAddr: dd.cc.bb.aa (old IP in reverse, should have been deleted)
DNSTTL: 600
structuralObjectClass: DNSARecord
entryCSN: 20091225133051.000000Z#00000b#000#000000
entryUUID: 77344376-85a5-102e-9deb-dbfa8f00ebbd
creatorsName: cn=admin,dc=work
createTimestamp: 20091225133051Z
modifiersName: cn=admin,dc=work
modifyTimestamp: 20091225133051Z


#2 was pretty much same situation, except this time only dns03.unix missed the 
deletion. There is nothing much in the logs on either dns03.unix, nor 
ldapslave03. But LogLevel is only set to "sync".

Is this related to:

http://www.openldap.org/its/index.cgi/Software Bugs?id=6059

it is peculiar that it is only occurring on delete records.
