I usually reset the rig a few times until it goes away. Sometimes, I see it going away on its own after awhile but then again the miner must have caught a GPU fault and restarted the miner OR..... SRR rebooted the rig for whatever reason.... just my guess. Hope we can get rid of it soon. I do see more occurrences of this when using Claymore ETH mining. I dont see it when using Optiminer (ZEC) or sgminer-gm (XMR)....
