Ho un java.nio.channels.SocketChannel nel mio jlamSI implamantation che si sta disconnettendo quando provo ad aprire un driver con dimensioni superiori a 4 GB. La RFC iscsi dice che BasicHeaderSegment.BHS_FIXED_SIZE può essere 48, quindi con questa posizione posso leggere i byte sul canale. Il documento java dice 5 tipi di errori, ma la mia app sta lanciando l'ultimo che non dice informazioni specifiche. 1 - NotYetConnectedException 2 - ClosedChannelException 3 - AsynchronousCloseException 4 - ClosedByInterruptException 5 - IOExceptionConnessione forzata dall'host remoto
public final int read(final SocketChannel sChannel) throws InternetSCSIException, IOException, DigestException {
// read Basic Header Segment first to determine the total length of this
// Protocol Data Unit.
clear();
final ByteBuffer bhs = ByteBuffer.allocate(BasicHeaderSegment.BHS_FIXED_SIZE);
int len = 0;
while (len < BasicHeaderSegment.BHS_FIXED_SIZE) {
int lens = sChannel.read(bhs);
if (lens == -1) {
// The Channel was closed at the Target (e.g. the Target does
// not support Multiple Connections)
// throw new ClosedChannelException();
return lens;
}
len += lens;
LOGGER.trace("Receiving through SocketChannel: " + len + " of maximal " + BasicHeaderSegment.BHS_FIXED_SIZE);
}
bhs.flip();
errore:
java.io.IOException: An existing connection was forcibly closed by the remote host

Grazie in anticipo, Felipe
Nota la correzione del titolo. Il tuo SocketChannel è ancora aperto. È la * connessione * che è stata forzatamente chiusa. – EJP
