If all servers are full and the request is queued in the backend's queue, then one server will pick the requests once available, regardless of the LB algorithm, so lbtot will not be incremented.

Re: The gap between ``Total'' and ``LbTot'' in stats page
I just recently upgraded my LBs to 1.3.15.8 from 1.2.something and noticed those stats. I was wondering about them as well. In my setup those numbers only seem to differ where I'm using cookies for persistence. James.
