One of our customer found that all the *.ntf files on Domino server will be automatically updated at around 5:00 AM. When you list *.ntf under Domino data folder by dir command, you will find that last update time of these ntf files are set as 05:00 AM like following

On this Domino Server the following default parameter is set in the notes.ini to start Statlog task at 5:00 AM by default, after statlog task executed, all the ntf files are updated.
*********************
ServerTasksAt5=Statlog
**************
Since there is no real design change in these ntf files, there is no deed to update these ntf files.
The customer wish HCL could stop updating *.ntf files during the execution of statlog task.
