Allright, pool at
http://gme.p2pool.nl and blockexplorer (
http://gme.p2pool.nl/chain/Gamecoins) are up again..
Regarding above question, I have no idea if and why it was at a different chain. It appeared to be stuck with the following message
09/07/13 19:02:04 ProcessMessages(ping, 0 bytes) : Exception 'CDataStream::read() : end of data' caught, normally caused by a message being shorter than its stated length
09/07/13 19:02:04 ProcessMessage(ping, 0 bytes) FAILED
Hope the lastest changes work and fix everything.
Cheers
