title: The query processor could not start the necessary thread resources for parallel query execution
body: <p>What does this mean and how to solve.</p>
  
  <p>I am running multi threaded c# application and this error happens when accessing database.</p>
  
  <p><strong>The query processor could not start the necessary thread resources for parallel query execution.</strong></p>
  
  <p>I am using "using statements" at every query so i suppose connections are getting disposed of after used.</p>
  
  <p>How can i monitor what is causing this ? This is starting happening after some time like at least after 1 hour.</p>
