WodVPN Channel hangs after a while (General questions)

I'm developing a client server application which works on WAN.
I'm using latest WodVPN.OCX v2.3.2 with Delphi 2010
I'm using WodVPN channels for TCPScoket communications.
I'm creating 10 TCPSocket connection in one Client to one Server every second (a client open and close 10 TCP connection in every one second (like http protocol) to server over WodVPN channel) and I'm transmitting all data with TCPSocket over WodVPN channel.
At first everything is fine but after a big while (after 30 mins to 2 hours) channel is not working but WodVPN communication stay fine, I can sendtext over wodVPN but channel not transmit any data and I'm seeing Receive Error on TCPSocket.
I'm trying to create a new channel and try to use it but new channel not working too.
When I recreate WodVPN object and open a new channel then TCPSocket transfer data and after a while channel stop again.
Do you have a solution for this problem?
