That message "was 3 bytes max allowable ..." means "SSL/TLS on a
plaintext port."

Newer versions of DS has a specific error message to explain this
better.

I think you should check your replication agreement configurations to
see if any of them list "ldaps://" instead of "ldap://"; for a StartTLS
connection perhaps. Or SSL vs TLS in the config.

Hope that helps,
