The man page says the state can be anything that netstat reports:

STATE=state

Causes only the sockets in the specified state to be included, "state" is
usually LISTEN or ESTABLISHED but can be any socket state reported by the
clients "netstat" command.


As long as netstat gives you CLOSE-WAIT, it should be possible to track it.
