When I assume the optimization happens, I get JSON decode failed(-1):wrong arguments. happened about 15 min in on one rig and about 30 min on the other. then continues to mine at same speed. and keeps saying Json decode failed every so often.
Happening on 1080ti and 1080 rigs.



For what mention here ... i think is some problem .. u have to check out a bit i did saw the above of ur reply on it .. out of 40-45 rig i run thru it i find out .. 1 of them totally cant run .. whenever it run it shut down i not sure what is the really problem .. but no problem running ccminer 2.2.5 .. and with the json error .. is more of a problem i find out of them if the gpu have no problem handling it .. it can give u a high speed .. let say 1 line of hash 1 line of json error but i did found when there is like 4 or 5 line of json error .. meaning it doesnt kick in on the right time the hash is so much lower .. but usual one have not much problem ..

lastly i find it will run into error every 1-2 day so .. have to check on it quite often ..
