It this point, I've got an open ticket with VMware trying to identify the issue.
We are currently focused on trying to rule in/rule out this KB issue: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2042874
My VMware support technician is in the process of trying to define what the net packet pools size should be set to in this scenario.
That is all I know at this point. Scott
