As you can see I have only 6 rejected shares on 1120 accepted one. I am very happy about that ratio!
Then without any further hint in the log file bminer creates new DAG:
[INFO] [2019-03-07T05:18:22+01:00] [D2] Creating DAG
right after that bminer creates a ton of rejected shares.
At 8:30 after about 3 hours I had about 90 rejected shares on about 1500 accepted ones.
I would be happy to get some information to circumvent this behaviour of bminer.
cheers!
