SMP Kernel Panic while heavy load.

[hshh]

As LI Xin's said,
I modified sys/kern/kern_descrip.c,
[root at www] /web/dump# diff -c kern_descrip.c.bak  /sys/kern/kern_descrip.c

  static int
  fdisused(struct filedesc *fdp, int fd)
  {
+       MPASS(fdp->fd_map != NULL);
          KASSERT(fd >= 0 && fd < fdp->fd_nfiles,
              ("file descriptor %d out of range (0, %d)", fd, fdp->fd_nfiles));
        return ((fdp->fd_map[NDSLOT(fd)] & NDBIT(fd)) != 0);
