I am solo mining with Ubuntu 16, Bitcoin Core 15, BFGminer 5.4.2-29, Antminer S3.
BFGminer is requesting a new block be created by the Bitcoin core every minute like clockwork.
Is this expected behavior?
This seems to be excess work being placed on the core for no reason.
Is there a startup flag for BFGminer to control this?

It seems the sequence of events should be...
- A completed block arrives in the Bitcoin core from one of the peers.
- Bitcoin Core notifies BFGminer of this blocks arrival.
- BFGminer sends a request to the core to create a new block from the available transaction in the Mem pool. CreateNewBlock
- Bitcoin core passes the new block to BFGminer, who then distributes the header out to the miners.

It seems that a CreateNewBlock would only occur when it is needed after a completed block has arrived. Can anyone shed some light on this process? Thanks.

Notice the block fees going up? Wink
