right after loading the ceres.json it crashes with this message

someone suggested this may have to do with numa cores on the threadripper?

edit: was solved by disabling numa cores

Worked around with commit 2f09a831099944951f0cfed1d4679a7ff1970c0e. Possibly affinitization will fail on some AMD processors, but will not crash.
