title: On running SonarQube and scanner I get "insufficient memory for JRE to continue"
body: <p>I have Sonarqube up and running with postgres db. I am using Sonar-scanner to scan for errors in multiple source codes which I have collected in another postgres db. As soon as I scan about 5 to 6 codes (each of around 10 lines maximum), the scanner starts failing with &quot;insufficient memory for JRE to continue&quot; error, not being able to malloc around 300mb of memory.</p>
  <p>Is there a way I can optimize sonarqube to minimize memory usage, as I believe it is eating up all my memory very quickly, perhaps by clearing cache etc. each time I run the scanner?</p>
  <p><strong>UPDATE</strong></p>
  <p>I updated my Java from java version &quot;1.7.0_95&quot; to java version &quot;1.8.0_77&quot; and now I get a different error saying &quot;Cannot allocate memory&quot; and the following:</p>
  <blockquote>
  <p># There is insufficient memory for the Java Runtime Environment to continue.</p>
  <p># Native memory allocation (mmap) failed to map 65536 bytes for committing reserved memory.</p>
