Run 8 died 54 s into its boot and this time bash named it: "176880 Killed" on the
run-canary line, which is SIGKILL. So the third failure mode is not an internal
fault - something outside the process is killing it.
And it is still not the OOM killer. Checked immediately after: oom_kill remained
0 and the allocation-stall counter did not move from 4421, so during run 8 the
cgroup never reached its limit (5.35 GB of 7 GiB), and the host had 13.8 GB
available. Two kills, no OOM evidence either time.
Rather than keep guessing after the fact, freeze_watch.sh now samples host
MemAvailable, cgroup memory.current and oom_kill on every poll and dumps the last
five samples when the process disappears - so the next occurrence carries its own
contemporaneous reading.
