title: Esper 5.4 java process High CPU usage
body: <p>We have upgraded Esper from 4.9 to 5.4 version. With <strong>Esper 4.9</strong> version we were facing Esper <strong>"out of memory"</strong> issue in our Application. Then we have upgraded Esper to 5.4. </p>
  
  <p>The Esper <strong>"out of memory"</strong> issue has been fixed but now we are facing <strong>High CPU Usage</strong> problem with <strong>Esper 5.4</strong>. Also facing the same problem with <strong>Esper 5.5</strong> version. </p>
  
  <p>We are using Java 8 version in our system.</p>
  
  <p><strong>Please suggest, How do I investigate:
  What part of the application or what thread is causing High CPU Utilization?
  And why am I facing high CPU usage problem with Esper latest version.</strong></p>
