title: Fallback disables - Hystrix
body: <p>I'm using Hystrix in my environment associated with Liferay and other external services. My circuit gets some fails and opens the circuit to a specific service. Everything is fine so far. However, the circuit never changes to closed again. My fallback is disabled with this property:</p>
  
  <p>hystrix.command.default.fallback.enabled=false</p>
  
  <p>What should I do to circuit checks that my service is working and change to closed again? I have verified the circuits with the Hystrix Dashboard.</p>
