Vmware VMXNET3 Packet Drop issue

We have a Windows Server 2008 Cluster that is virtual. An issue we traced back to dropped heartbeat packets. Then we came across Vmware KB2039495.

We tried adjustments as indicated, but can still stress it to discard packets.

Has anyone found the magic setting to elminate this VMware driver issue?

This was a good sugestion! We had a while back a similar poblem and I think the solution was to change the NIC driver used. Also, before you do so, make sure VMware Tools is correctly installed and updated - vmware tools is important when using vmxnet NICs.

At last, are packets being dropped at OS level/Virtual layer, Firewall/router/switch level?

Thanks

Hi

We are testing the captain obvious solution of using the E1000 and so far so good.

The discards are occuring on WIN2008 Servers from driver buffer only
