MRT_DROP spam my sys log

Hi, does anyone know why this is spamming my system log?
I have Home Assistant running a samba share, tried disabling that now to smoke out whats causing this...

Wed Dec 16 10:30:01 2020 user.warn igmpproxy[4382]: MRT_ADD_MEMBERSHIP failed; Errno(19): No such device
Wed Dec 16 10:30:52 2020 user.warn igmpproxy[4382]: MRT_DROP_MEMBERSHIP failed; Errno(99): Address not available

Did also a igmpproxy restart. It's been quiet for 15 minutes.
