EOF while receiving data from socket.

I found that in a TCP connection the java captured EOF exception(0 returned while reading or receiving) while receiving data from remote server and closed the connection, but from the tcpdump, the local side had been receiving data, I don't understand why the application would receive a EOF error.

This often happens when the peer was receiving data at extremely slow rate, but this doesn't look like the case.

I appreciate any comments on it, Thanks.
