TCP connections don't time out for lack of activity. I see below that you've
tried
to fix the problem by enabling the Keepalive timeout on the socket, but I'd
be surprised if that fixes the problem, as it essentially does the opposite
of
what you want: it forces the kernel to close the socket underneath your app.
if the TCP stack gets no response from the other end of the connection.

If your connection is "going to sleep", what actually happens in your
program,
when you try to send, or expect to receive, data ?
