Why would these arp requests occur as a steady stream, all going to
primarily one machine it looks like? This just started today. I
usually see an occasional flash of the activity light on the cable modem
but the activity light is almost burning steady now. Here is a snippet
of output from tcpdump.

It seems to me that there is some problem here. How would you suggest I
approach the cable company with this information?
