Out of curiosity, is this a very new version of dnsmasq? or an older
version? I ask because there have been some fixes and regressions
related to dnsmasq updating its configuration and responding to
machines appropriately. A version might be helpful, just to enable
those of us who are curious to go double check things at a minimum.

So I strongly suggest you look at the last_error field on the node and attempt to determine why the failure happened before retrying.
