title: Memory leaks icCube 6.8.5
body: <p>After a few days we experience severe memory leaks that effectively halts our icCube server. We have only 4 schemas with estimated memory usage of 1551MB, 878MB, 1017KB and 1284MB. We have 72GB physical memory. The last memory message in the log is:</p>
  
  <blockquote>
    <p>free:5184MB / total:120GB / max:120G</p>
  </blockquote>
  
  <p>After restart and some hour and half the memory usage is a lot less: </p>
  
  <blockquote>
    <p>free:34.3GB / total:50.0GB / max:120GB</p>
  </blockquote>
  
  <p>We are using icCube 6.8.5. This is our memory setting: <code>-Xms50G -Xmx120G -XX:+UseG1GC -XX:MaxGCPauseMillis=500</code></p>
  
  <p>Please advice.</p>
