Yes, but what caused that packet to be sent?  Plainly, with only a single
machine (and all others correctly configured) you'll never see the error. 

If you've got one machine configured to do DHCP, you've probably got
several - and so if two boot at the same time you have the conditions to
generate the error.

On the other hand, this isn't really a plausible explanation for
"overwhelming" numbers of errors - unless perhaps the DHCP server is dead.
