Yep,
Sure do...sometimes we'll even see little solderballs that have come out
through the via's on the backside of the board.
Putting more paste down won't help in my opinion, it'll just flow through the
board and come out through the via's on the backside. I went to Anaren's web
page and the layout and footprint on this board is exactly what Anaren says
it should be. Go to:

They say the more via's the better to minimize ground inductance and improve
ground continuity...
