Is there some flaw in the dhcpd bpf rules? I suspect that the dhcp server set the interface to promiscuous mode so it can listen for broadcasts. Tcpdump sets up an interface for promiscuous opertion and when you exit tcpdump it returns it to non-promiscuous operation. Killing and restarting your dhcp server after exiting tcpdump should solve your problem, as it will set the interface up for promiscuous operation again.
