Hi, I think your platform doesn’t have more than 1 NUMA node (node 0. See message " NUMA node(s): 1"). And you are giving ‘-n 4’ in command line. That might be the reason this warning is being reported before defaulting back to node 0.
Does this create any function issue?

Don't forget information about environment (platform, 'cat /proc/meminfo', etc). More the info about what you have attempted or trying to attempt, easier it is to point out possible problem area.
