For the texture cache db, by default Kodi checks if the original image which was used to populate the cache has changed on a 24 hour interval.

Quote:9. If it’s been at least 24 hours since the texture was last loaded, we check whether or not the cached version needs to be refreshed from the original image. If so, we cache the image as outlined above.
I assume this is designed to check if images have been changed on online databases. However it also seems to apply to images which are stored alongside the media files.
This check causes unwanted daily disk spinup for users with large libraries stored across dozens of disks on unstriped arrays (unRAID etc).
My request is to allow this check interval to be set by the user in advancedsettings.
