I've been asking around for a crash/hang detect and auto restart solution but there doesnt appear to eb anything.

I was using Claymore and getting 136MH off 6 x Gigabyte 1060s and with EthMiner Im getting 151 MH!

So definately worth sticking with Ethminer so long as it doesnt crash.  In 3 days i've had 1 crash that was alerted to me by ethermine.org emailing me to say my miner was offline and it was errors in the CMD window with machine not hanging so I just remoted in and restarted but I still lost an hours mining
