Message:
I am getting the same issue.  Not sure if it is related to 2918714 - note
that is also on AIX.  Volume I am testing is 11TB in size.  I added some
debug output as follows;
void get_path_stats (struct parameter_list *p, struct fs_usage *fsp) {
  p->total = fsp->fsu_blocks;
  /* 2007-12-08 - Workaround for Gnulib reporting insanely high available
  * space on BSD (the actual value should be negative but fsp->fsu_bavail
  * is unsigned) */
  printf("PVJ %g %g\n", fsp->fsu_bavail, fsp->fsu_bfree);
  p->available = fsp->fsu_bavail > fsp->fsu_bfree ? 0 : fsp->fsu_bavail;
Output is:
PVJ -NaNQ 1.51616e-314
