Perseverance pays off in the end. Having worked out how the socket class
was supposed to work it seemed that the select call was returning when
it was not supposed to and giving a false indication in the socket set
of who spoke. When I looked at the return code of select() it was -1
(interrupted).

All communication is appreciated. I often find just trying to explain a
problem can lead to fixing it. Sorry this is a bit rambling.
I know D is not done yet and there will be bugs. I don't know yet if its
me or D.
The program structure is quite simple.

Hi!
I see.
I think my previous answer was a bit naiveI didn't appreciate the full scope
of the problem. Sorry for that, but you know, internet is fast, snap snap : )
Ok, for now I'm afraid I don't have any more to add. (An isolated example would
of course help greatly!)
All I can say is, i
Hi Heywood
Thankyou for your time. Yes I agree making the call blocking does stop
the exceptions churning. Unfortunately the application stops accepting
data now because after the first incoming transfer from the web socket
client it sees data on the listening socket and promptly blocks on it
and
Hi Bob!
My guess: You're listener is set to be non-blocking. That means that when you
call listener.accept() it will return immediately with an
SocketAcceptException, if there's no connection. And you're basically calling
listener.accept() over and over again in an infinite loop.

Hi all,
This is a long shot but I'm out of ideas. I ported an app from Windows
to Linux and after many issues it is working but I'm left with a strange
problem. The app basically reads data streams from a USB device,
processes them and outputs real-time graphical data to a browser. There
