In the morning I get an exception in the Websphere FFDC protocol. Please tell me what this exception is?

I wrote a basic servlet suitable for delivering a stream of data (in some test cases, a 14GB text file) to a client:

  protected void doGet (HttpServletRequest req, HttpServletResponse or respectively) throws ServletException, IOException    resp.setContentType ("application / byte stream");    or setContentLength (-1);    InputStream = null;    Try        OutputStream os is the same or getOutputStream ();        int transfer units = -1;        byte [] buf corresponds to new byte [65536];        is = new FileInputStream ("D: /largetext2.txt");        ((Transfer units while = is.read (buf))! = -1)            os.write (buf, 0, transfer units);            //os.flush ();             catch (disposable e)       e.printStackTrace ();     last        will            close();         catch (IOException e1)            e1.printStackTrace ();                Try            or getOutputStream (). close ();         net (IOException e)            e.printStackTrace ();             

So, you’re just making a simple query. I have checked if the GET request for the servlet is being made by the Java client using URLConnection and anywhere from the Chrome browser. Both handle random transfers from 1MB to 90MB, then the download stops, although the client search stops, the private bytes of the java.exe process from the WAS servers continue to grow (from 300MB to 950MB) the device will give the following stack trace:

The Java client just gets stuck when making a read request, whereas Chrome often supports downloading without knowing that the server has aborted everything, according to the experts. This often leads to strange timeouts or problems with the IBM servlet container.
