CLOSE_WAIT after restart

Perhaps this is more a Linux question than a LMS question ... anyway ;-)

I'm running LMS on a Raspberry Pi with Debian Wheezy, LMS latest version.

When I restart my LMS ('service logitechmediaserver restart'), I find usually a remarkable number of TCP connections marked as "CLOSE_WAIT", most of them to the players.
Is there a more gracefully way to restart the server, so it would close the sockets before quitting?
