[Help-gsl] gsl_multimin_fdfminimizer quits too early!

When I try to minimize a function of 2 variables, it seems to quit after
only a couple of iterations even though the gradient in one direction is
still huge

gsl_multimin_fdfminimizer_gradient(s) says the gradient is: 149.996,

I am using
    const gsl_multimin_fdfminimizer_type *T;
    gsl_multimin_fdfminimizer *s;
T = gsl_multimin_fdfminimizer_conjugate_fr;
s = gsl_multimin_fdfminimizer_alloc(T, 2);
gsl_multimin_fdfminimizer_set(s, &F, x, .1, .1);

Does any one have any idea why it would quit so early?
