I do not see in the trace, I think that systemd-machined stops on it's own after
a period of inactivity.

I don't see this either... (the log is fairly long and hard to read, so maybe I missed it).
I only see systemd-machined exiting. DEFAULT_EXIT_USEC is 30 s, and it exits 37 s
after startup, consistent with that timeout.

Can you post the full cgroup tree before systemd-machined exists and after (systemd-cgls
output)? You might want to disable the watchdog for systemd-machined (by adding
[Service] WatchdogSec=0 to a drop-in file for systemd-machined), and then stop
it with sigstop, and see if your machines still get killed.
