Sometimes it will start after a profit switch cycle and then nothing happens. It will shows the first few lines of the miner running with no errors but nothing after that as if it waiting for something. This last time it was running find and it showed it had accepted 44/44 blocks but then it stopped for a long time. You can see before that 42/44, 43/44, etc.
Is it possible there is nothing else to mine (i.e.: issue with MiningPoolHub?). Shouldn't it pull something else at that point? Not sure what the X or X (X/X) denotes.
Earlier today as well, I don't remember what was on the screen but it had been sitting there doing nothing for who knows how long. The GPU was at 1% so I know it wasn't mining anything.
Soon as I stop and restart the miner, it starts working fine again.
I have noticed this too with ccminer, I think it does have some stability issues. And its specific to which coins too, switching from and going to. I haven't had time to track it down but at a glance I think it is when its going from nist5 to another coin. Oddly enough it only happens with 2 of my rigs out of 73 rigs. Its not overclocking, memory or undervolting related. Tried all different options with it, just those two rigs, screw up ever now and then.
