If you're stuck in CLOSE_WAIT, it's a bug in your software: You've received a fin and need to close the socket if you're done with it.
The socket should be marked ready for reading, but when you try to read you'll get zero bytes back: Something in your framework may not realize that -- truss/strace the process and I'd guess you'll see a 0 byte read followed by not closing it; alternatively you may not be polling the socket for read availability?
Some things would change if you intended for the socket to be half closed, but I don't think you do?
