This generally means that the remote side closed the connection (usually by sending a TCP/IP packet). If you're working with a third-party application, the likely causes are:
You are sending malformed data to the application
The network link between the client and server is going down for some reason
You have triggered a bug in the third-party application that caused it to crash
The third-party application has exhausted system resources
