Hi,
I am renaming a file in Java on Linux O/S. The function renameTo returns true but file does not get renamed half the time. The file resides on a mounted folder on Linux machine. The code is below:

        // Rename the file with an appended .LOAD extension, so that next time
    // this program will not pickup the same file again
      String renameToFile = filename + ".load";             //filename is valid file name
      File sourceFile = new File(filename);
    if (sourceFile.renameTo(new File(renameToFile)))
    {
     //success, verify now
      File destFile = new File(renameToFile);
      boolean renamed = false;
      while (TIMES_TO_RENAME_VERIFY-- > 0)             //5 times
      {
        try
        {
          Thread.sleep(RETRY_WAIT_TIME); //wait to confirm renaming        6000ms
          if (destFile.exists())
          {
            renamed = true;
            break;
          }
        }
        catch (InterruptedException ie)
        {
          log.exception("File rename wait exception ", ie);
        }
      }

      if (renamed)
        log.info("Successfully renamed the file " + filename +
                            " to append .load at the end");
      else
      {
        log.error("Failed to verify renamed file " + filename + ".load"); //this is the error I get
              return;
      }
    }
    else
    {
      log.error("Unable to rename the file " + filename + " to append .load at the end");
      return;
    }
