Hi Jeremy.  What do you mean by "traffic captures"? Wireshark? Or Level 
10 logs? Or both?  Although this problem was reproducible, it cropped up 
in a production environment and so I can't really ask the user to 
intentionally disrupt work again.

Thus, i need to investigate another way to reproduce the issue. It 
seemed to be related to "time".  However, it might have been related to 
"amount of data transferred" or something else that RISES WITH TIME.

I would also, of course, like to know if Windows clients are effected.
