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.

Personally I'm still quite a fan of CSN - I don't think they're too old at all.
