Hello Hartmut The mailing list address changed a while ago, there's an additional "lists." in the domaine name.
Regarding your question, I would assume you are running in a cgroup with the second NUMA node disallowed (while all the corresponding cores are allowed). lstopo with --whole-system would confirm that by showing disallowed stuff.
