My first thought was the box thought it was being attacked, but I am unsure if this is the case and if so how to rectify it.  It will go green for a short period of time, and then go back to a warning state and start flapping.  It is green / OK maybe once a day.

I don't think that your box "thinks" it's beeing attacked because of an 
ICMP-Packet or two.
I had a similar issue, and it was a routing problem. I had an OK-State 
as long as i kept pinging the servers, if I didn't do that, traffic 
wouldn't find it's way to the host (or back, I'm not sure anymore).
