Well it would seem that a restart on BFGminer has fixed the problem, but I've never had to do that before...
Hmmm... My big issue with revenue decline comes from the fact we aren't solving any blocks. I haven't done any digging, but some posts have said other pools are slow too...
If the entire network is actually slow that means perhaps the last difficulty adjustment was too aggressive. From what I understand, difficulty (technically) can move up
or down, whatever it takes, with the end goal being that the next 2016 blocks take 2 weeks to mine. Not saying the last difficulty increase was flawed or too aggressive, but if this is a network-wide issue we should expect to see it reflected somehow in the next difficulty calculation.
Makes sense but they don't seem to know why this is happening and here is an exact copy off the BTC Guild site:
A block was paid out twice earlier today due to a severe slowdown in the bitcoin daemon used to scan for new blocks. This block has been removed from the payment history and the shifts since it was already paid once. Rewards will have decreased by 1 block for all users that were active between shifts 14027 and 14036. This should not materially affect overall rewards for any users. If a user's balance has gone negative as a result, it is highly unlikely their balance will remain negative by the time those shifts are closed due to additional block solves.
The exact reason the bitcoin daemon became so slow is not known, but secondary checks have been put into place to prevent a double payment from happening in the future.
