title: Maven compilation dies with "Killed"
body: <p>I am running a Maven2 compile of a large Java project on a linux virtual machine<br/>
  Compilation is failing with the following error "compiled with -X for debugging"</p>
  
  <p>[DEBUG] Source roots:<br/>
  [DEBUG]  /home/{...}/src/main/java<br/>
  [DEBUG]  /home/{...}/target/generated-sources/meta<br/>
  [INFO] Compiling 1377 source files to /home/{...}<br/>
  Killed<br/>
  (and I go back to bash prompt immediately)</p>
  
  <p>I figure this could be:</p>
  
  <ul>
  <li>A linux thing (I checked that my ulimit -Hn is okay, 10000)</li>
  <li>A VM thing (this in on an amazon EC2 ubuntu instance)</li>
  <li>A maven / java thing (Never seen this kind of death, usually just out of memory errors and the like)</li>
  </ul>
  
  <p>Any thoughts to narrow down the culprit?</p>
