Has anything of note happened before this started happening, eg a scheduled upgrade? I wonder if it’s related to this issue with dhcpcd, in which dhcpcd would seg fault and take the OS offline, in response to certain unusual broadcasts exhibited by some consumer routers. It only started happening in the latest Debian Buster-based environments. I appreciate it’s FlightFeeder but I’m assuming it’s pretty much the same as PiAware under the hood. The bug was patched by the dhcpcd maintainer and the OS no longer drops off the network as a result, but the patch has yet to find its way onto systems.
