Have you ever seen runts on your switch interfaces? What is that? A runt is a packet that is less than 64 bytes long. So, really, this is a problem. In my case, on the server (which I just inform the server guys at this particular customer). See below. Notice that the runts and the input errors line up. In this case, its a server issue. But keep in mind, you dont really want to see these runts on the switch. Call the server guys and get them to figure out what is going on. They probably want to know about it anyway.

Good catch!! Most likely a NIC issue...either a physical issue with the NIC (replace it), or an issue with the driver software (update it).
