This error seems to occur randomly. In this case it was the 2nd GPU on a computer with a pair of matching 1080 Ti's. Once it occurs that GPU stops mining and does not restart.
This computer was mining BTG using your Eco (min PL) settings. Usually closing miniZ and restarting it and it runs
What caused it? Is there anything I can do to prevent it?
Adding a watchdog to miniZ might resolve these kinds of stoppages.
