The first question is this:

mod_backhand is peer-based.  The byAge rule says to not use servers that 
are not running (you haven't heard from in 5 seconds).  So, in the 
example you gave, web2 is up, running and announcing that it is okay to 
receive traffic.  So, why is web2 failing to service the request?
