Today got an error
OpenCL on GPU one crashed. Watchdog exited but the miner is unable to restart. Hands whole system.
Any solution?
Power off / Power on... Not what you wanted to hear but... It's a solution..
I get the same problem occasionally, Try looking at the problematic card, Down-clocking it etc.
I think this is more random problem. I upgraded drivers from 16.7.3 to 16.8 and it worked well over night. I guess it will keep on working well. I was thinking about using -r option to set 30 min time to force reboot and then keep bat file in the startup with delay of 30 sec. But that means I will lose 3-5% mininig time further.
But anyway, so far so good.. it is working for now

thanx for your advice
I have a similar problem.
Gpu 4 failed in open cl call , after a time this freeze the system.
Some time the gpu work for a hours and sometimes for a few minutes. Your udgrade drivers?
