In my experience, it is a matter of someone else on the net chewing it up. I will regularly get hundreds of these messages. It is nearly always when the network gets VERY busy, or during (what our engineer referes to as) packet storms. One of our legs on the base network has an intermittent short that nobody has been able to locate, and it causes serious problems for all of the users on the net. I see the messages, and confirm that other folks in the subnet are having problems too. If I ever see this while everyone else is having no problems, the most messages I ever get is one or two. From everything I have seen, the only difference between the old behaviour and the new behaviour is that the new behaviour puts up a warning message when it dumps the packet, instead of not notifying you. As a rule, I have ignored the messages reasonably safely. -- ------ TSgt Dave Burgess NCOIC AL/Management Information Systems Office Brooks AFB, TX
