title: Activity Monitor Problems in SQL Server 2005
body: <p>I am looking at the Activty Monitor for SQL Server 2005 and we have some processes that are taking up large amounts of the CPU. When I look at what is trying to be run I get:</p>
  
  <pre><code>set transaction isolation level  read committed 
  </code></pre>
  
  <p>This code is not coming from any of our applications.</p>
  
  <p>What is causing it?</p>
  
  <p>What should be done?</p>
