Seen twice today. Once mid-run: thirteen passes, then the process ended
with no summary, no failure and no receipt. Once from the start: the
first test ran 35 minutes against a measured 4.5 and was still running
when it was stopped.
Ruled out rather than assumed: not memory (84 GiB free, no OOM), not the
daemon (the stalled machine answered `incus exec` immediately), and not
the changes under test — the anchor VM had no host log and no
containers, so the run never reached placing the host.
What changed just before is that the rebuild went from two artifacts to
six, and every one of them is pushed into the scenario's registry, which
is the step the second stall sat in. Recorded as what changed, not as
the diagnosis.
The reason this is an issue and not a slow test: the suite prints
nothing between starting a scenario and finishing its first test, so
four minutes and thirty-five look identical from outside, and the only
recourse is to guess. That is how a workstation was left unbootable in
August. And a run that ends silently after thirteen passes is a run
somebody may believe.
