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 vzkernel-2.6.32-042stab090.1. Install all pending updates and reboot the host to apply them.
