Guys becareful the new mine by yvg-1900 seems fishy, I'm running it on 5 of my servers and non are being registered at ypool. Its running pretty fast and finding shares I doubled checked my worker name and password and everything else is working.

I am looking at ypool and non of the servers are connected, my worker is not even active wtf...

Reverting back to the old miner I don't know who got those shares but I am sure I didn't.

He can keep that 10% gain in col/min I don't need it.

Try checking your params. I had same problem because of -m512 param. After I had removed it worker connected to ypool normaly.
