One of the things I wondered about is whether it'd be better to deploy a 10-node ring or split it into 2x 5-node rings. Sounds like splitting it up might not be a bad idea. How often would you see those sync problems (and were they the same errors as I posted or something else)? And were you running poolmon from every node when you were seeing sync errors?
