Looks like it.
Is this behaviour an artefact of the coin itself or something else?
I don't know, maybe the zero-bounty-blocks confuse the pool software? My p2pool runs without problems so far. I lowered the fee to 0.0 % to offer new users a stable pool to mine on as long as the other pools are this unstable.
Switched to your pool and already got my first payout. P2Pool rocks.
wzttide, question about payments if I may - do you make payments every block? If so is there any way to hold off payments into larger amounts? As I have a pretty low hashrate, per block payments are tiny, and I'd prefer to wait for 0.1 or even 0.25 payouts.
