C:\Users\Desktop\Ethmining\Claymores\nodevfee.exe EthDcrMiner64.exe -epool asia1.ethermine.org:4444 -epsw x -allpools 1 -dcri 1 -altnum 1 -esm 1 -ewal 0xxxxxxxxxxxxxxxx.Miner01
Only work with esm 0 or without this parameter (default = 0). -eworker xxx are not supported 
You tested it? Different packet structure from using -ewal WALLET.WORKER? I am seeing lot of stale shares. Is it possible this program increasing stale share rate?
