In a class of direct gauge mediation with a perturbatively stable SUSY breaking vacuum, gaugino masses vanish at the leading order of SUSY breaking F-term. We study the allowed parameter space of the gauge mediation models. By imposing a Tevatron bound on the lightest chargino mass $ {m_{ ilde chi_1^pm }} gtrsim 270;{ ext{eV}} $ and a warm dark-matter mass bound on the light gravitino mass m3/2 ≲ 16 eV, we find that almost all the parameter space is excluded. Near future experiments may completely exclude, or possibly discover, the scenario.
