I am not sure if this is docker specific or cgroup comes into play.
The measurement is implemented in docker CLI, but I would make the
assumption
that the eviction is done within the cgroup scope.

The increase pattern is "incremental" until the huge eviction, and this is
my question.
Couldn't also the eviction happen incrementally rather than 15GB of file
cache evicted on an instant?

Not any error in the logs, unfortunately (or fortunately).
Seems like this issue <https://github.com/hashicorp/nomad/issues/16230>, or
the parent one <https://github.com/moby/moby/issues/10824> that everyone is
linking to this.
