take a look at the changelogs. many reasons to upgrade, especially syncrepl/syncrov and contextcsn -related bugfixes.
Is there any larger tolerance can be configured ?
Besides upgrade to 2.4.11, any other alternative method ? It's because we have gone through many testing in 2.4.9, if change to 2.4.11, need to re-test all again.
Thanks
absolutely sure? timeslices needed for mmr in 2.4 are very small so all servers have to be in exact sync. maybe you should check/recalibrate and refill the dit again.

Dear all,
I am using openldap version 2.4.9, I am using 4 ldap servers with 4-way master configured.
Data can be synronized initially, but when the records is getting more and more, now is around 100k records, I always find data is not synronized between the four ldap servers.
I find that "CSN is too old, ignoring" in the LDAP log file.
