dude, the evidence as said is that the sum of "accepted" blocks of the two DevFee workers reported in miner status page, was in some case nearly half of my main worker URL! Some other miners reported "just" 20-25% of DevFee blocks...
Hey esol. Similar to the other board member here, I am not seeing the same issues on my test miner as you are. The disconnects on the pool db you showed are very strange. Not sure what else to say!
Would be curious to see your settings you used...
I have been an awesome miner user for many years now and have no reason to think anything shady is going on here.
