We consider the possibility of a bosonic (meta)stabilization of a cosmic gauge string loop due to the presence of a gas of low-mass bosonic particles which become trapped within the string core. This boson gas exerts a pressure which tends to counteract the string tension, allowing a circular string loop to find a finite equilibrium radius, provided that gas particles do not escape the string core. However, high-energy bosons do escape, and, consequently, the loop shrinks, and the temperature rises. Estimates indicate that the bosonic stabilization mechanism is ineffective, and the loop is unstable against decay.
