Checking NUMA statistics we can see that there are a lot of misses and foreign usage is also high:
# cat /sys/devices/system/node/node0/numastat numa_hit 103033484350 numa_miss 1025085 numa_foreign 13609467 interleave_hit 106250 local_node 94623448085 other_node 8411061350
Misses and foreign calls are miscalculated by the kernel. This issue has been recognized as a bug with an internal ID #PSBM-26309.
This issue is fixed starting from kernel
