Hi there,
I have found strange behavior for my mixed rigs. It works quite good for at least 1-2 days, but got a lot of invalid shares (nvidia gpus mainly) after then. It took 2 days, 3 days or more often even 4 days without any invalid share and after that fall down to approximately 60% efficiency (valid/invalid shares for the whole mixed rig). After reboot it works as before, no invalid shares for several days and then the scenarios repeats again:
Any hint please?
