If you search the list for any older version you will see a consistent
recommendation to upgrade to the latest version (currently 2.4.36) and
see if the problem persists.
If you use RHEL/CentOS you can find packages here:

So you're running MMR and seeing issues about "old" CSNs and don't see
the
potential relevance of a change log that references:
Fixed slapd syncrepl updateCookie status (ITS#7531)
Fixed slapd syncrepl for old entries in MMR setup (ITS#7427)
...maybe they're your issue, maybe they're not, but in the amount of time
you need to simply read this you could find a 2.4.36 package.

Hi all,
I have upgraded to 2.4.36 openLDAP version. The problem still exists.
It seem to be appear less than before. This week this problem occur only
once.
To resolve this problem i'm doing:
stop slapd on ldap that haven't entry
and launch it with
/usr/local/openldap/libexec/slapd -c
rid=201,dsn=20131003140020.844217Z#000000#002#000000 -h "ldap://:389
ldaps://:636" -F /usr/local/openldap/etc/openldap/slapd.d -u ldap -g ldap
-l local4
rid number is my source syncrepl
dsn is 20 seconds before the problem ( retrieve from entryCSN in question )
is't the good way to do

New subject: Antw: Re: another CSN too old N-WAY master
Hi!
Are you sure you are chasing a real problem? AFAIK, in multi-master sync, the
server that receives a change will send that change to all other nodes, which,
in turn, will also send the changes received to all other nodes. That means
that the original submitter of the changes will receive ist own change.
I also think that "too old" means "not newer" here. I wonder if the
message
shouldn't be dropped instead of complaining that the requested change is
already there.
The gurus may correct me if I'm wrong.
Regards,
Ulrich

It would be pretty inefficient if a provider in a MMR setup receives its own
modifications.
Given the fact that I'm also seeing missing entries in a MMR setup I suspect
there are indeed problems with the contextCSN.
Another one ITS#7710 which likely is limited to use of slapo-memberof but I'm
not really sure about that. (The data consistency issues happened without
slapo-memberof.)

It would be pretty inefficient if a provider in a MMR setup receives its
own
modifications.
I agree, but from the logs my version seems to do exactly that, so maybe my
config is not correct, or the software has a bug. As it still does what it
should do, I don't care about the bug for the moment...
Given the fact that I'm also seeing missing entries in a MMR setup I
suspect
there are indeed problems with the contextCSN.
Another one ITS#7710 which likely is limited to use of slapo-memberof but
I'm
not really sure about that. (The data consistency issues happened without
slapo-memberof.)
Ciao, Michael.

This bug ( for me ) appear on "ou" with more than 120K entrie. Every entry
is check by another application every hour.

You could try to compile OPENLDAP_REL_ENG_2_4 branch snapshot from git.

If a server is receiving its own modifications that means your serverIDs are
not configured correctly. If your serverIDs are not configured correctly MMR
cannot work correctly. Fix your configuration.

It could be due to an older version (openldap2-2.4.26-0.16.1 of SLES11 SP2)
being used...
