Multi-Wan not removing down connections.

[marcot1]

I'm having issues with 2 firewalls (redundant w/ CARP) that will not remove a Time Warner cable internet connection when it goes down.  I've unplugged the cable modem from power as well as unplugging the coax but leaving the network connections up and the result is always the same.  100% packet loss and a 0ms ping time and the connection is being listed as "Online" and not being removed from the gateway groups.  Any ideas would be appreciated.
