Kernel: in_scrubprefix: err=65, prefix delete failed

I noticed that when I disable carp on the secondary or primary I get an error in the system logs.  I have 3 interfaces with 2 using carp.  One of the interfaces is a sync interface. I have 1 carp vip on LAN and 1 on WAN interface but I have a few alias IPs on the WAN Carp IP.   I just started testing 2.1 with carp so I do not know if it has always done this on 2.1.  It does not happen on the stable 2.0.3 version though.

I don't see any issues so I assume it is nothing to worry about but I figured I would report it anyway just in case.  I google search mentions something about removing ipv6 route or something and it appears right after the link state goes down so maybe it is a timing issue or order issue of something being done.  I do not use ipv6 btw.
