We seem to have got a bug in sendfile(2).  Besides bin/89100, there
is kern/92243 on it.  The problem is rather unpleasant and it's in
the kernel, not in ftpd(8).

Would you mind trying the attached kernel patch?  Note that you'll
need to rebuild the modules along with the kernel after applying the
patch.  Thanks in advance!

Thanks for the patch it seems to work:

fetch  ftp://test:[EMAIL PROTECTED]/usr/src/test.zero

test.zero 100% of 4293 MB 4255 kBps 00m00s

The patch is against HEAD.  In case it fails to apply, just change
the type of the 2nd argument to vnode_create_vobject from size_t to
off_t in the .h and .c files -- that's the essence.
