I trying to investigate more and more and i see that i cannot open new sockets on the server, it refuse the connection, below is the packets captured in wireshark : Document joint : spuriousretransmission.pcapng
The application i openned who crashed all the twsocket open two new socket on this server ! And in netstat the server socket are still in listenning state, (it happen on localhost and from a remote computer). Moreover the last 4 connection are in FIN_WAIT_2 Maybe it is a start...

If I understand you correctly, you want to keep remote TCP/IP sockets connected for several days at a time, presumably over a LAN or maybe a WAN? There are so many ways a connection can be lost, routers and switches, hardware issues, software interference, Windows Updates, etc. Even with keep alive, TCP/IP sockets can say connected but not be, the only reliable way is to send and echo data, a proper handshake. The probability of it being a bug in ICS that no-one else has noticed is highly unlikely, but not impossible, as explained previously I did fix a timeout issue that caused a socket to be closed earlier this year, which I found in one of my applications. You really need to find a way of bullet proofing your application, so it reconnects if nothing is received for x second/minutes/hours, or use regular handshaking for a more reliable and shorter timeout.
