Hi!
After upgrade from 3.3.0 to 3.3.2
the following error logs appear in the maas rackd.log:

2023-04-27 10:57:30 twisted.internet.defer: [critical] Unhandled error in Deferred:
2023-04-27 10:57:30 twisted.internet.defer: [critical] 
	Traceback (most recent call last):
	Failure: twisted.internet.error.MulticastJoinError: (b'\xe0\x00\x00v', b'\n\xd9\x0c\x02', 98, 'Address already in use')

strace:

[pid 2810] setsockopt(21, SOL_IP, IP_ADD_MEMBERSHIP, {imr_multiaddr=inet_addr("**224.0.0.118**"), imr_interface=inet_addr("172.17.0.1")}, 8) = -1 EADDRINUSE (Address already in use)

And the following error logs appear in the maas regiond.log:

Seconding this problem. (MAAS 3.3.3) Multicast join does not work as intended with multiple interfaces and RackDs (we have 3) are not stable (services flapping constantly) - Would love this to be resolved. Stable provisioning of machines is not possible like this.

I have added my voice to the pertaining bug:
