Another situation I just noticed.   Hashunit #1 is showing in the UI as "Inactive" .  Hashboard #0 is active in the UI.    In checking the bottom of the board #1, all four lights are flashing like it is hashing.    When I looked at the mining pool console, it looks like I only have one hashing board mining. 

I hit the restart button in the Miner dashboard and when the mining restarted the second hashboard showed up in the UI as active and it looks like it is mining at the pool with both hashboards now.
