I’ve just set up carp (for the first time) and it seems the virtual address is not being removed on the backup host:

May 23 20:55:09 xxx kernel: carp: 1@igb0: INIT -> BACKUP (initialization complete)
May 23 20:55:12 xxx kernel: carp: 1@igb0: BACKUP -> MASTER (master timed out)
May 23 20:56:33 xxx kernel: carp: 1@igb0: MASTER -> BACKUP (more frequent advertisement received)
May 23 20:56:33 xxx kernel: igb0: deletion failed: 3

ifconfig shows the address as active:
# ifconfig igb0
igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=e527bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
	ether ac:1f:6b:12:34:56
	inet 212.12.xxx.xxx/24 broadcast 212.12.xxx.xxx 
	inet 212.12.xxx.yyy/32 broadcast 212.12.xxx.yyy vhid 1 
	inet6 fe80::ae1f:6bff:...%igb0/64 scopeid 0x1 
	carp: BACKUP vhid 1 advbase 1 advskew 200
	media: Ethernet autoselect (1000baseT <full-duplex>)
	status: active
	nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

Is there a configuration I can/need to adjust?
