Have you ever implemented central DHCP server for all of your network (VLANS), and you used a command "IP Helper-Address? The ip helper-address will actually forward many other UDP-based broadcasts to the address specified as tft, dns, time, netbios-ns, netbios-dgm, tacacs, bootpc, bootps etc.
Many times it is generating unnecessary traffic for your DHCP server. Have you applied "ip forward-protocol udp ...." command to prevent this?
