Our company has a mobile app with clients connecting via sockets through AT&T's 3G towers in San Francisco. Lately I've been noticing some sockets never close - FIN_WAIT1 and TIME_WAIT is common. I've even seen sockets open > 24 hours. And of course the client's are not actually in the app as we've not received updates from them.
Is it possible to force-close them? And if anyone has experienced this same thing over AT&T 3G, I'd appreciate any advice you can give.
Thanks for your time.
