I am mining on dwarfpool and the monitoring page is showing that the miner has not been active for 6 hours,  but claymore is working normally and accepting shares from dwarfpool.  Is this something to be concerned about or are they stealing my hashrate right now?   I am also mining decred at the same time on suprnova and the decred pool is showing my miner functioning normally.

What is going on?  Is this a website glitch? or are they stealing my hashrate?
