Eloquent.
We use CARP in a lot of places. It's nice. Not as "cool" as
wackamole from the concept side -- much more of a VRRP
implementation. UCARP looks neat. Freevrrp does pretty much the same
thing as far as I can tell. When my OS doesn't support it on the
driver level, I like to use wackamole -- the protocol is much more
loose and allows for some "interesting" manipulations.
Each tool has its own strong points, so to each his own.

That message means that it was not about the shutdown the interface
because it couldn't find it.
Is there a problem manifesting other than the log message? Interfaces
plumbed that shouldn't be or interfaces that should be owned yet
aren't visible via ifconfig?
I'll look at merging back in some fixes to the ife-sockpacket stuff
(Linux specific ifconfig-like subsystem). This code was adopted by
another project and evolved considerably -- I'll go peak at that and
see if any serious fixes were made.

Make sure the ports are more than "2" apart. Spread uses port and port
+1, I believe.
For safety sake, I launch my spread rings at +10 +10 +10.
so ring one will be :4803, ring two will be :4813, ring three will be :
4823
