The effect of critical current noise on the phase-slip- rate in an overdamped Josephson junction is calculated. A significant increase of the Kramers escape rate is predicted for submicron metal-insulator-metal junctions. The temperature dependence of the rate shows deviations from the Arrhenius law at low temperatures if the junction conductance fluctuations are produced by quantum ionic tunneling processes in the junction barrier. Implications for magnetization decay in high-T/sub c/ superconductors are discussed.
