Scheduler log is very verbose

The scheduler log is very verbose. For example the log entry

15:32:35.109 10000 7973.B7D0F8E0

{scheduler.file_order} read_new_files /home/virtual/ftp/input
15:32:35.109 0 7973.B7D0F8E0 {scheduler.file_order}

read_new_files /home/virtual/ftp/input 0 Dateinamen gelesen

appears every 10 seconds. Periodically written log-entries should be filtered by a log level.

The log entry is "0 Dateinamen gelesen" should not appear in the log.
