title: Quartz job does not fire, often
body: <p>I'm using quartz 2.2.1 and Spring 3.2.5, both in a Maven / war project.</p>
  
  <p>My war-file deploys fine under apache-tomcat-7.x, and the logs
  indicate that all of the quartz jobs are loaded.  Here's where
  the trouble begins.</p>
  
  <p>Several jobs fire as determined by their triggers.  But consistently, in many instances, the trigger does not fire the job when it should, and
  other times does fire the job as expected.  Why?</p>
  
  <p>It's as if quartz has a bug interpreting triggers -- especially when
  triggers result in multiple jobs at a single time-slice.  (Eg, on each
  10th minute of the hour, 3 different jobs should fire).</p>
  
  <p>Can anybody explain what's going on?  To my thinking, there should
  not be any missed triggers at all.</p>
  
  <p>Thanks.</p>
