title: How to stop an unstoppable zombie job on Jenkins without restarting the server?
body: <p>Our Jenkins server has a job that has been running for three days, but is not doing anything. Clicking the little X in the corner does nothing, and the console output log doesn't show anything either. I've checked on our build servers and the job doesn't actually seem to be running at all. </p>
  
  <p>Is there a way to tell jenkins that the job is "done", by editing some file or lock or something? Since we have a lot of jobs we don't really want to restart the server. </p>
