It sounds, then, like it 's a 'bogus' error - or at least shouldn't be in the 'Administrative Attention Required' view.
What version of Domino are you running? I seem to recall seeing a message lingering around in the 'Administrative Attention Required' view that I no longer see at 9.0.1FP3, but I can't be sure that is exactly the error being discussed.
Another thing that I ran into one time was somehow the AdminP database was changed to a previous level design, . You might refresh/replace if it's not 9.0.1 (8/01/2013)
BTW, we're running managed replicas, and it's working OK here.
