Poolerino, would you mind setting up a chat session with other USDE pool ops, including steady, coinarmy and pooligans, to centrally come up with some sort of a fix re: double payouts, or whatever the issue is? Perhaps try an older version of Stratum? Getwork? Set your crons to run less frequently? The update coming out shortly should address a lot of the issues that pools have had.
Pool Owners: If these (possibly MPOS and/or stratum) problems cannot be identified or fixed, we'd like to kindly ask that you direct users to use the P2P pools until we work together to implement source code updates.
One of my teammates at SteadyMining has found the reason for MPOS performing double payouts yesterday morning, and has created a workaround in mpos source.
However, he states, a fix would be needed in the wallet code to make changes to MPOS unnescessary.
Please contact us through the chat on our pool (Right bottom corner), or host a chat somewhere we can join. We'd like to shed some light.
