I had this sort of thing happen almost two years ago on a 2650 with apf (prior version). We do have it runnning on a few Dell boxes (750, 1850, and 2650) with out an issues today and on version back. I doubt it would be kernel related. What are the settings in your conf.apf? Anything in the logs? Some cron job firing off when it happens? Do you have something feeding it a block list of sorts? What is the USE_AD= setting set at? Have you asked Ryan @ rfxnetworks? I believe that is his name anyway.

Has anyone had this issue themselves, or does anyone successfully running Cent0s 4.X with the 2.6.9-42.0.2.ELsmp kernel have a sample /etc/apf/config.apf I could take a look at?
