title: "No free license" error in Crystal Reports
body: <p>The following error message occurs with some reports of our Crystal Reports application, when you try to open them a second time.</p>
  
  <pre><code>"A Crystal Reports job failed because a free license could not be obtained
  in the time allocated"
  </code></pre>
  
  <p>It seems to be a problem only with some reports (with a lot of data in particular). Other reports work without any problem. But once the error message appeared, all reports will fail.</p>
  
  <p>Can anyone tell me how the licensing mechanism of Crystal Reports works?<br>
  Where is the "free license" obtained from?<br>
  Can this be a time issue due to the amount of data?</p>
  
  <p>-- edit --<br>
  From what we learned in the meantime, it seems to be a problem only with reports that called a particular long running PL/SQL package in the report command. And Crystal somehow doesn't like calling that twice.<br>
  And i guess the error message is just a secondary symptom and not the cause.</p>
