Non stop arp broadcast for gw and dns

my routerboard (RouterBOARD 962UiGS-5HacT2HnT) non stop sends "who has" requests for the gateway and dns ap adresses .The arp table however is correct.
The device is in bridge mode. I have a simple one segment LAN and acting (Internet) gateway is an EdgeRouter 4.

The requests are for the ip adresses of the gateway and dns which are on (a switch on) eth1. I wonder why the routerboard is broadcasting for exactly these two adresses only.
