Description

the refresh() method DU is as follows,

  @Override
  protected synchronized void refresh() {
    try {
      duShell.startRefresh();
    } catch (IOException ioe) {
      LOG.warn("Could not get disk usage information", ioe);
    }
  }

the log warning message should also be printing out the directory that failed.
