Ключевой момент — использование опции copytruncate

       copytruncate
              Truncate  the original log file to zero size in place after creating a copy, 
              instead of moving the old log file and optionally creating a new one.  It can be used
              when some program cannot be told to close its logfile and thus might continue writing 
              (appending) to the previous log file forever.  Note that  there  is  a  very small time 
              slice between copying the file and truncating it, so some logging data might be lost.  
              When this option is used, the create option will have no effect, as the old log file 
              stays in place.
