title: Jenkins jobs going missing
body: <p>I have a heavily parallelized build across 45 slaves (one master that just handles launches).</p>
  
  <p>The problem I am running into is that about 3% of the jobs disappear.  </p>
  
  <p>The project setup is a "master" job that then launches (via the parameterized job plugin) N jobs across N slaves.  Most of the time, the console output for the master job is correct with regards to job numbers of the distributed build steps.</p>
  
  <p>Occasionally, however, the job indicated in console actually belongs to a completely different build.</p>
  
  <p>Where do I even start looking to track this down?  The jenkins logs are eerily empty of any information about failed jobs or problems launching jobs.</p>
  
  <p>My best guess at the moment is that the missing jobs were actually queued waiting for executors when something happened to remove them.  But I have no evidence to support this.</p>
  
  <p>Thoughts, suggestions, helpful links all greatly appreciated,</p>
