Those logs mean the connection (e.g. conn=1125) got closed.
Would you grep conn=1125 in access log ?

This message is harmless. It means that some values of nsds50ruv in the 
RUV have identical referral.
This should not occur, but replication is smart enough to just log this 
warning and continue working.

I would not recommend cleanup right now. Just clarification of the status.
Would you send all the ruv values returned by 'list-ruv' (here there is 
no duplicate).

thanks
