I bet that if you fill all memory on the non NUMA setup
it will crash too.

e.g. run something like this

#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <stdio.h>

#define MEMSIZE
main()
{
unsigned long len = (sysconf(_SC_AVPHYS_PAGES) - 10)* getpagesize();
char *mem = malloc(len);
for (;;) {
memset(mem, 0xff, len);
printf(".");
}
}
