We have a couple HP Procurves.  I don't believe that they are managed,
at least I have never gone in there and managed anything.  Do I sound
like a newbie?  I'm not a young pup, I just don't know anything.

Thank you for your help.  it took a while, but it seems that our
streaming users plus our reporting tool are causing the spikes.  Once
we stopped our streaming usage and when a meeting got out(they were
using the reporting tool)  we dropped down to a manageable trickle.  I
really hate to have to tell our users that they can't stream.  We have
some diehard Pandora fans, and I believe that music can help the work
environment.
