There are any number of causes including the remote server closing the socket, a switch or hub between here and there is bogged down by backup traffic, or a segment your connection passes through became too busy with higher priority video traffic. The actual details are difficult to determine and none of the administrators involved will ever admit they had a problem. In most cases the TCP/IP error will simply tell you it timed out waiting for a response. Your code should be able to re-open the connection at this point and resend the message that triggered the error. Then resume working on the rest of your list.
