By default, sure; but there are options to deal with it.


copytruncate
  Truncate  the original log file to zero size in place after cre-
  ating 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  (ap-
  pending) 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.  The copytruncate option allows storing rotated
  log files on the different devices using olddir directive.  The
  copytruncate option implies norenamecopy.
