    Hello,
    
    This is my first post here, so bear with me.

    Red/Code Red II/Nimbda Policy-Map on my external router since August 17th,
    and this machine was installed post August 17th.

    Anyone seen this behavior before? Any suggestions? I am going to flush and
    fill, but I'd like to learn something from the issue, rather than just have
    it be an exercise in the format command!
    
    Thanks.
