This is a log from a nexus 5596 running 7.1(4)N1(1). It's part of an OTV deployment (multicast based). 

2023 Jan 31 16:04:26.827 PLSWCR01A %ARP-3-REQ_NON_AM: arp [3558] Sending ARP request for 10.68.127.11 on invalid interface loopback1 request from pid: 3606
2023 Jan 31 16:06:31.289 PLSWCR01A last message repeated 174 times

Any idea why this is happening?
