This appears to be a rare problem. I've never seen it, and I'd guess that 
nobody else on the mailing list has either. So we'll need your help to debug 
and fix it. It's quite likely to be a configuration error in dnsmasq.conf.

Please could you capture some of the traffic that appears when dnsmasq is 
running, and attach excerpts from your system logs (especially regarding 
dnsmasq) and your dnsmasq.conf file?

dhcpcd is a DHCP client daemon, its functionality does not overlap at all with 
dnsmasq. Did you mean dhcpd? I personally find dhcpd too heavyweight for a 
small network, and dnsmasq has some very nice and useful features such as DHCP 
and DNS integration that make me prefer it.

Cheers, Chris.
