Anyone have any tips on how to get SGminer to stop hanging during pool switches?
It doesn't always hang but occasionally does. When it hangs I can't even pkill the process and have to walk to the rig and press the power button.


Ubuntu 16.4
AMD cards
Using https://github.com/tpruvot/sgminer
my conf is -
{
  "pools": [
    {
   "poolname" : "myriadcoin-groestl",
   "url" : "stratum+tcp://hub.miningpoolhub.com:12005",
