After DEVfee on Ethereum rejected, we have to restart miner?
No, you don't need to restart it. "DevFee: stop mining" means only that it stops mining for devfee (after 36 or 72 seconds of devfee mining), it does not stop main mining.
Rejected shares is a compatibility issue of my miner, I'm working on this issue, I'll post an update in several hours.
Thank u for that i have to restart the miner every 2h or so.
and please watchdog option that would help allot.
