Trond, What is the set of patches that are you testing? I'd like to give that a spin tonight as well. It is possible that what makes my configuration more susceptible to the problem is the fact that the client significantly overpowers the server: Athlon x2 4200+ with 2Gb of RAM for the client vs. PIII 1Ghz 512 MB RAM for the server. They both have gigabit ethernet and both NICs and the switch support jumbo frames.
