Hello, @todxx ! If one card crashes, miner stops finding shares on all gpus, but continues getting jobs. is there a way to avoid this?

That is rather odd and should definitely not be happening. Can you tell us a bit more about your setup?
Which OS version are you using? What version drivers are you running? Which version of the miner are you running?
Do the stats still display when you press 's' ? How do you know if it's just one GPU that crashes?
