Did you read all the above messages of this thread?
I have the exact same issue of the thread owner. And the answer of your question is in the above replies.
Also, I already said that even if I restart the entire rig after about 3h the gpus continue to mine, the power consumption and temperature remain the same, the miner log write the proper hash rate, but the pool stats just record the first 3h of mining and then it doesn’t see the rig anymore, until i reboot it and then it just receive again the first 3 hours of shares.
