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. Chris
