Which version of expect are you using?  The stock one
has a bug which causes occasional spurious failures,
described in http://gcc.gnu.org/PR12096
(I haven't seen the one you're seeing, but then, I've never
  used FTP as a transport when using dejagnu).
The patch
http://kegel.com/crosstool/current/patches/expect-5.39/pr12096.patch
fixes those problems for me.

Also, you might consider using rsh as the transport; see
http://kegel.com/crosstool/current/doc/dejagnu-remote-howto.html and
http://kegel.com/crosstool/current/doc/chroot-login-howto.html
for how I set up things when I was using dejagnu.

Finally, don't forget there's a dejagnu mailing list; see
http://lists.gnu.org/mailman/listinfo/dejagnu
