[go-nuts] How to detect and/or log tcp connection state

I am working on a high volume (7-10k reqs/sec) http application that is at
times getting overwhelmed with occasional traffic spikes during peak
traffic times. When this happens, the number of CLOSE_WAIT connections
grows into the 10s of thousands, Reducing tcp kernel timeouts helps
recovery, but right now I am totally reactive and using linux command line
tools to monitor. I would like to detect this situation in the application
where I can remediate. Is there a way to hook into the tcp state
transitions in the app? RIght now I start a http ServerMux using
ListenAndServe(). Do I need to roll my own? Any tips or links to docs would
be appreciated.

Thanks in advance!
