woke up this morning and all my erupters were lit up
i could not connect to my raspberry pi using VNC so i had to restart it.
i tried starting cgminer the usual way but it just hangs for a few minutes and all the erupters light back up?!!?
cgminer -o stratum+tcp://nl1.ghash.io:3334 -u ********* -p *********
tried a couple of different pools but still the same. its been fine up until today!
