Getting emails about multicast?

Hi,

I'm not a super expert when it comes to networking, but I keep getting emails from my Proxmox server and I'm not quite sure why. Here are the emails in question:

I know that 224.0.0.1 is a multicast address but why do I keep getting these emails? I would appreciate any suggestions or ideas anyone has.

Thanks.

Hnm, it seems to have increased in duration, spamming my email every couple minutes now.

I'm open to any suggestions anyone has.
