I am running aroun 4k pps myself and not a block found since 3 am. I also have the processes spread over 4 separate boxes so it has to be REALLY bad luck, or someone is just growling up all the blocks (I think BlastBob prob runs around 100k pps right now)..
Not just Blastbob 
.. Running 60K here.. Still finding blocks but there's still 30-100 blocks between the blocks I find.Dwaynnmmm I'm still trying to break 1k here. No where close!
