I was getting stale shares from 9%-38% with SmartCoin w/ my 4 rigs/workers - now back hooked up to pool straight, I'm at 0.10% ...is this a known side-effect of running SmartCoin? I don't know how much extra is going on behind the scenes with processes, etc. I do know how much I dig SmartCoin though - will keep updating.
This isn't a known side effect of smartcoin. I run 3 instances per card normally with less than 0.05% rejected shares. Its normal for rejection percent to start a little higher and then settle out sometimes though. Can you give me some information on how you have things set up?
How many instances are you running per card? And to how many different pools? Which miner? etc.
