Just for completeness, is this on Openstack? I can see that code doesn't buffer anything when a port is plugged-in, so each triggers a reload. Could maybe tweak things there to wait a few seconds between the HUPs. I'm not sure it's a bug in dnsmasq though. -Brian _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
