      I'm testing Log4j RollingFileAppender with log4j 2.6.2.

      I want to rotate the logs every minute and so I have a log4j2.xml very similar to one example of here https://logging.apache.org/log4j/2.x/manual/appenders.html#RollingFileAppender. This is my log4j2.xml

      <?xml version="1.0" encoding="UTF-8"?>
      <Configuration status="warn" name="testlog4j2" packages="">
        <Properties>
          <Property name="baseDir">C:/tmp/testlog4</Property>
        </Properties>
        <Appenders>
          <RollingFile name="RollingFile" fileName="${baseDir}/app.log"
                filePattern="${baseDir}/$${date:yyyy-MM}/app-%d{yyyy-MM-dd-HH-mm}.log.gz">
            <PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
            <CronTriggeringPolicy schedule="0 0/1 * * * ?"/>
            <DefaultRolloverStrategy>
              <Delete basePath="${baseDir}" maxDepth="2">
                <IfFileName glob="*/app-*.log.gz" />
                <IfLastModified age="60d" />
              </Delete>
            </DefaultRolloverStrategy>
          </RollingFile>
        </Appenders>
        <Loggers>
          <Root level="ALL">
            <AppenderRef ref="RollingFile"/>
          </Root>
        </Loggers>
      </Configuration>
      

      And this is an app where I write a log every second.

      package testlog4j2;
      
      import org.apache.logging.log4j.LogManager;
      import org.apache.logging.log4j.Logger;
      
      public class TestLog4j {
      
          private final static Logger logger = LogManager.getLogger(TestLog4j.class);
      
          public static void main(String[] args) {
              try {
                  for (int i=1; i<=240; i++) {
                      logger.info("Hello");
                      Thread.sleep(1*1000);
                  }
              } catch (Exception e) {
                  //e.printStackTrace();
                  logger.error("Excepcion general", e);
              }
          }
      }
      

      What happens is:

      once the system rotates the log at the first minute appears continuously errors like this

      2016-07-28 15:10:02,015 Log4j2-Log4j2Scheduled-1 ERROR Unable to move file C:\tmp\testlog4\2016-07\app-2016-07-28-15-10.log.gz to C:\tmp\testlog4\2016-07\app-2016-07-28-15-10.log.gz: java.nio.file.NoSuchFileException C:\tmp\testlog4\2016-07\app-2016-07-28-15-10.log.gz -> C:\tmp\testlog4\2016-07\app-2016-07-28-15-10.log.gz
      

      There isn't a gz for every minute
      The result gz don't have a log with 60 lines. Instead they have 1, 2 or three lines of log.
      The main log C:\tmp\testlog4\app.log has no content

      Thanks
