title: Log4j DailyRollingFileAppender concurrency with multiple processes
body: <p>I have a number of identical processes that are writing to a single log file using a Log4j <code>DailyRollingFileAppender</code>. I am concerned that multiple processes may try and roll the file and that chaos will ensue. Does the implementation allow for this using with some kind of locking mechanism? - the <a href="http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/DailyRollingFileAppender.html" rel="nofollow noreferrer">Javadoc</a> doesn't mention it.</p>
