We are running application written in C# under .NET framework under Windows CE 6.0 on our hardware based on LPC3240 with PHY DP83848I. This application communicates with PC over Ethernet. Everything goes well when there is other activity on Ethernet. When we have quite Ethernet (no communication from other nodes) our application stops after couple of hours, e.g. every 2 hours. If during stop state we do ping against our IP address it continues to work. On Ethernet where other packet activity happens our application was running 10 days without any stop. Does anybody know what can be wrong? --------------------------------------- Posted through http://www.EmbeddedRelated.com

I have an embedded system that opens a pipe to a Win PC and we have to make sure that we send a handshake every 30 seconds or so, so Windows doesn't close the socket and free the resources. Obviously if you are opening and closing the sockets as needed, this wouldn't be an issue. You did say that it appeared that if ANY activity was going on everything continued OK, so maybe it is some type of switch issue where the switch is doing something funky during quiet periods. Get a sniffer on one of the nodes and see what is going on. Wireshark is free.
