Intel 10Gb on VMware (AMD) ESX 4.0 intermittent problem

 We had this once before on an Intel GigE ethernet adapter..
The hacky fix was to leave a ping running continuously (mtr in this case) which solved the problem.

Sounds like a arp/mac learning issue-- I think it got fixed when we re-installed ESXi on that machine.
