title: kill -QUIT: log not getting appended
body: <p>I have a Java process. I am using <code>log4j</code> for logging purpose. I have specified in <code>log4j.xml</code>, location and name of log file. logging is working fine. I have problem with <code>kill -3</code> logs here. </p>
  
  <p>I trying to get process-dump using <code>kill -QUIT &lt;pid&gt;/ killl -3 &lt;pid&gt;</code>. I expected the dump generated by <code>kill -3</code> to get updated in log file specified in <code>log4j.xml</code>. </p>
  
  <p>But it is not happening that way. I need the dump to observer thread statuses. I do not know any other way to get process dump of a running process. </p>
