Definitely not what I was expecting:

    if (len > GUESTFS_MESSAGE_MAX) {
      fprintf (stderr, "guestfsd: incoming message is too long (%u bytes)\n",
               len);
      exit (EXIT_FAILURE);
    }

Are you using two radically different versions of libguestfs on the
client and server?  (It would have to be really different versions,
since it is a long time since we broke backwards compatibility)
