title: SonarQube exits with 143
body: <p>I am trying to Setup SonarQube on Centos 6 VM with 6GB of RAM. The process always exits with 143. </p>
  
  <p>On analysis I found that the JVM is being sent a SIGTERM signal and thus exiting. There are no core dumps and dmesg is also quite unhelpful. I also tried fiddling with the Memory options to no avail. </p>
  
  <p>If some can help me debug this issue it will be quite useful. At least, I will have some idea why this software is being terminated.</p>
