Personally, I don't think that this is an Oracle problem. You have a network connection that is unable to keep up with demand. I've seen that happen with application servers like WebLogic which request large amounts of data from the database and are on 1 GB LAN. Another example is when a slow PC is trying to pull a huge extract or report from the database. That can be helped by making the IP queue size longer.
