ПЕРЕБРОБОВАЛ:

DataOutputStream вместо OutputStream
Убрать хедер Content-Length
Писать по 512 байт

Так

                    output.write(data, 0, data.length)

И так

                for (int i = 0; i < data.length; i++)
                    output.write((int)data[i]);

Так

                    for (int i = 0; i < data.length; i++) {
                        try { output.write(data[i]); }
                        catch (IOException ioe) {
                            i--;
                        }

Т даже так

                    for (int i = 0; i < data.length; i++) {
                        try { output.write(data[i]); }
                        catch (IOException ioe) {
                            output.close();
                            output = net.openOutputStream();
                            i--;
                        }
                    }

Что безрезультатно.
