Hi Gatra & Co.
I'm excited to be back to work on our stratum mining pool. At first glance everything appeared to be working. However after running for a while longer I noticed in increasingly terrible rate of invalid shares. Restarting the miner seems to do the trick but of course we don't want to require such frequent restarts!
We're running gatra's fast stratum miner and stratum pool. In some early runs we had vardiff enabled and saw the server re-target client difficulty. The xptminer didn't seem happy about that so we disabled it and still have poor performance. Is anyone else using the new stratum xptminer and open source stratum miner?
nonce-pool, do you all see any similar problems?
Note the miner runtime in the brackets below. Computer C is much faster but it also degrades to a terrible rejection ratio
