I have a datacenter with so many machines (blade computers) in it that dnsmasq couldn't keep up and we ended up having really bad UDP storms. That wasn't fun to debug at all since we had no idea that dnsmasq would have scaling issues like that. Even worse is that the logging output is abysmal and made things even harder to diagnose.
Switched to another DHCP server and the storms went away, but I am not entirely happy with it because of the way it handles leases, it doesn't guarantee that each MAC keeps the same IP over time.
Now, I'm always on the lookout for a good DHCP server... tried another one that was golang, but it wasn't working on my network for some weird spec reason, I didn't have time to debug it and the authors didn't seem that interested in helping out.
