Open Stack

Hi Steve,

Thank you for your feedback.

I figured out a solution for the problem. In my case the root cause lies in
NUMA Topology, the memory slots was not physically split up evenly across
the processors, so i disturbed them accordingly and everything works fine
now.

Thanks again,
Hamza
