Another possible solution, which avoids shutting down Koha altogether, 
is to tweak the logrotate config to use the "copytruncate" setting.  So 
instead of all the prerotate/postrotate stuff, just do this:

/var/log/koha/*/*.log {
    rotate 5
    weekly
    missingok
    compress
    delaycompress
    notifempty
    copytruncate
}

Here's what the logrotate man page says about copytruncate:

  copytruncate
         Truncate  the  original log file 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  log-
         ging  data  might be lost.  When this option is used, the create
         option will have no effect, as the old log file stays in place.
