Hey everybody,
Quick qn!
I've got 20 grid seeds connected to the raspi via a powered USB hub and its been hashing well for a couple of days. Just yesterday, the hash rate dropped significantly to around 2/3 of what it used to do.
Upon inspecting all the Gridseeds, I noticed that the lights were all flashing but when I did a screen into each individual miner, some were not able to find any blocks.
Any idea why this may be happening? Could the Gridseeds be faulty or is this caused by something else?
Very strange indeed...
Cheers
