    Typically this happens if you are Generating Video Preview Thumbnails or Chapter Thumbnails:

    If you use the thumbnails - those images you see on some clients when you fast forward or rewind - they are quite handy. I love 'em. If you don't use them you can disable the generation of them, or set up the server to only generate them during scheduled maintenance - when you're sleeping or something.

    Other things that can cause CPU activity are: Standard Scheduled Maintenance like Deep Analysis, Library Updates, Cleaning of Bundles, Database Optimization (all quite important - and should be done regularly), or possibly even syncing media to devices and/or Optimizing Media.

    Sometimes if you have this activity in progress you can find out what it is by viewing 'Status', and sometimes it's a complete mystery. Check your Maintenance Tasks (all of those should really be checked) and the times Maintenance is done. A few hours each day is usually all that's necessary. Also adjust the generation of thumbs to happen when you add media or during Maintenance.
