4.7 kernel doesn't contain 71c799f4982d ("mm: add per-zone lru list
stat") so the OOM report will not tell us whether the Normal zone
doesn't age active lists, unfortunatelly.

You can easily check whether this is memcg related by trying to run the
same workload with cgroup_disable=memory kernel command line parameter.
This will put all the memcg specifics out of the way.
