[Dnsmasq-discuss] Infinite loop in dnsmasq v2.86?

[Byrne, John]

On freshtomato 2021.8, I'm occasionally seeing dnsmasq lock up and spin on a core in the router. I don't have a reproducible case, yet. The last one that occurred was reasonably soon after boot, but I forgot to increase the size of the log so I don't have all the logging output since boot. dnsmasq.conf (without the dhcp-host lines) and filtered logs attached. The DNS cache seems the obvious suspect, but I none of the more recent changes is leaping out at me.

Thoughts on how to debug this? I've got the freshtomato docker build working, so I can build a version of dnsmasq to test with.
