If you convert min.rst back to pdb and look at it, is anything odd? I
wonder if you have a bond through a ring or something. Note that in your
min.output, the atom with GMAX is
H13 13967
and before that it was nearby atom
O24 13965
I would look in that area of your pdb for clues.
Also you might try starting temp of 1K to see what happens.
