Public bug reported:

We've been seeing things that appear to be races between the hosts files
being written out for dnsmasq and dhcp requests coming in. We will get
occasional errors from dnsmasq saying "no address available", "duplicate
IP address" but by the time you look, the corresponding host file has
long since been replaced.

Outputting the dnsmsaq config file in the debug logs would help in
establishing what the DHCP server state was at the time of the problem
