"Last" status indicates a system boot every few hours

Afternoon! I have some weird behavior with the last command here on an openSUSE Leap 15.5 (headless server) box.

It seems that the system is continuously logging kernel startups. You can see that when I reboot the system (at 16:12) all of the entries turn to “reboot” surprisingly.

Is there a reason that the system is continuously logging “startups” throughout the day? Am I polling last incorrectly?

Thank you for any help!
