Netboot keeps rebooting my attached MOX - or do i read the logs wrong?

Hi together, please have a look on attached logs, and tell me if this is normal. It keeps rebooting my netbooted MOX - netbooted from Omnia Turris - is this something i can ignore? I think not, cause i see traffic freezes and it looks strange to me that it repeats so often. Any advise is appreciated. Thanks!
