          Yes I got exactly the same, the problem is as everyone is accessing the environment via ipsec tunnels or the ssl vpn all it takes is for one user to do a download and everyone's sessions jump about or die totally :(

                    Can you test there to see if its a 5.x issue then?

                    Rather keep it in a VM than on physical hardware for the flexibility :)

                      Yeah I am willing to give that a go, but I need to drive a way to the DC to do the upgrade that's why I was asking if anyone had tried it, I didn't want a wasted trip :)

                          Try the 4.1 instead.

                          It could be interesting to see if its a 5.x issue.

                            I was on 4.1, I just went to 5.1 :)

                            Its not as bad with 5.1 and 5.1 seems to manage the cpus much better all machines are using less but it is still unusable :(

                                  It would appear that I have resolved this in my situation anyway.

                                  It turned out to be the physical nic setting in vmware was set to 100meg full duplex.

                                  I changed this to auto negotiate and it still negotiates to 100meg full deplux but the problem totally goes away!!

                                  If I switch it back to specifying 100meg full duplex I get the problem again so it is defiantly that setting.

                                  Thanks for the help Supermule

                                  So if anyone is having similar issues check this setting!
