Can you please actually ask a question rather that just posting logs @aslinkipfs? Thank you!!

I guess the question is: what does it mean? why it occurs?
I have this problem(error log) today too.
I guess it is because: I restart daemon without stop miner first.

When I restart lotus daemon, the error log disappear.

Restarting the daemon will certainly result in errors like this on miner instances that are still running but should stop once the daemon has been restarted. It needs to be a quick restart to avoid any less solvable miner issues!
