My mistake I thought 0.0.0.0 was coming from the default route.
I’ve initiated a DHCP connection on my v3Beta10 box with “dhcp debug packet” turned on and I get the same as in your listing, so this looks like it’s just a normal DHCP conversation.
I’d guess you’re getting some kind of Broadcast storm from a misconfigured client or virus infected PC.
