Can you also test with /sys/kernel/mm/ksm/merge_across_nodes set to 0 (and KSM enabled normally) and confirm this is a KSM+NUMA issue?

Another way to potentially cause this issue to occur faster would be to set:
/sys/kernel/mm/ksm/sleep_millisecs to a value lower than 200
or
/sys/kernel/mm/ksm/pages_to_scan to a much larger number than 100

Thanks,
