Which one is now the official client? The one on http://i0coin.bitparking.com/ or the one at https://github.com/kR105/i0coin/ ?
My pool is using the one on http://i0coin.bitparking.com/. I've been unable to get the kR105 one to work consistently. It slowly disconnects all the peers over time. I assume this has something to do with the DoS code - it doesn't seem to like existing peers. I had the same problem trying to port i0coin to a recent bitcoin as well so I don't think it's a bug with the kR105 code specifically.I've had the same problem with disconnects using i0coin v32509. I'm guessing the problem could be that i0coin has only a few nodes at this time and doesn't have a list of seed nodes or a fallback node list. Try using -addnode or -connect. Longer term we need a list of reliable nodes stored in the client (https://en.bitcoin.it/wiki/Fallback_Nodes).
