ive got a customers s9 in my datacenter that stopped hashing what i noticed is on the system tab , under overview were it says kernal info its saying socket error refused to connect or something to that extent ( should have taken a screen shot ) anyways the miner is not hashing and is not showing a red light.
i rember seeing something about this issue in this thread somewere but i cant seem to find it now


any idea on what i need to do to fix this , so far a reboot has not helped
