thanks. I see where it's crashing. Could you compile this code on your
box with

  gcc -o foo foo.c

and provide the output?

  #include <stdio.h>
  #include <kstat.h>
  #include <sys/processor.h>

  int main(void)
  {
    int cCpus1 = sysconf(_SC_NPROCESSORS_MAX);
    int cCpus2 = sysconf(_SC_NPROCESSORS_CONF);
    printf("%d %d\n", cCpus1, cCpus2);
    return 0;
  }

Furthermore, could you provide the output of

  kstat |grep "cpu_info.*instance"|wc -l

?

Thanks,

Frank
