title: rails delayed_job memory consumption problem
body: <p>We're having huge problems with the delayed_job plugin - <a href="http://github.com/collectiveidea/delayed_job/">http://github.com/collectiveidea/delayed_job/</a></p>
  
  <p>When we start tasks with "ruby script/delayed_job start", the process never lets go of RAM it acquires.</p>
  
  <p>So it starts with 10%, 25%, gets to 80% and never lets go of the ram, even if it has no jobs to process.</p>
  
  <p>Any ideas how we can get over this?</p>
  
  <p>Thanks!</p>
  
  <p>(PS: RAILS_ENV=production script/delayed_job start didn't work for us to start the delayed_job worker)</p>
