The problem seems to be solved, although I will know for sure over the 
next couple days.  I am now using my full pipe and everything seems to 
be working.  I enabled RED on the big queue, queue1.  I also set the 
default queue(queue0) to priority 7, and dropped the qlength back to 
default(50) on both queues.  Everything seems to be flowing smoothly but 
I will probably do the ACK prioritization after I see how it runs like 
this for a day or 2.  I don't like to make too many changes at one 
time.  In essence, I think the default queue being set at high priority 
has the same effect, but I have to read a little more about it to ensure 
that is the case.  Thank you everyone for your help on this.  I really 
didn't want to have to switch back to 4.11 for this project.
