Sorry, bad joke, but there is no way for me to do that research, as Dell servers are warrantied for a max of 5 years from date shipped from the factory, so I would need to know when you bought it to be sure it's not past that. All of ours went out last year. If you have warranty coverage through the end of 2014 you must have bought the last one 
My post was more to state that we aren't seeing the issues you are, so it may be a combination of variables in your particular environment than a general bug in ESXi's networking, but you probably already gathered that from the blog post.
I'm not sure why you would assume that because your experiencing an issue in your environment everyone else is as well. We don't have multicast packet loss, or any other type of packet loss, beyond what you would normally see for link congestion or other normal packet drop situations, unless we are dealing with faulty hardware or cabling. Andy yes, our NOC and network engineers know how to use packet sniffers. We are a financial institution, and we run many of those applications your referring to, and are pretty sensitive to our applications not working as expected.
Without knowing what steps support has already had you try, it's hard to suggest what else to do. Moving the vm to another hardware combination is a quick way to rule out firmware and nic driver issues, etc. Depending on how much effort you want to continue to put into chasing the issue vs reverting to a dedicated physical, you could replace VMware's generic DVS with the Nexus 1000v and see if it exhibits the same behavior. This would also give you more visibility to track the packet activity inside the virtual switch.
