Subject: CSN too old

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.

Any idea of this kind of error and how to fixed it ?

Thanks
