This won't solve your problem, but connections in TIME_WAIT state aren't
open anymore ;)

The socket info is kept just for being able to receive any "lost" and
"detoured" packets from the network for that connection.

There's Linux kernel parameter tcp_fin_timeout which you can tune lower -
that closed sockets connection data would be cleared out sooner.

Reducing this for LAN networks shouldn't be much of a problem, as generally
the packets there don't get detoured and lost that often.

I have never changed it myself though, don't have an idea about its side
