Software caused connection abort: socket write error

843790Mar 6 2008 — edited Mar 6 2008
Hi all,

I have that "Software caused connection abort: socket write error" exception error that i've never meet before.
When I try without using SSLSocket, I have the same "Software caused connection abort: socket write error"
What does it means ?
What is going wrong with my code?

Here is the code I wrote :
//server side 
GZIPOutputStream gos = new GZIPOutputStream(child.getOutputStream());
GZIPInputStream gis = new GZIPInputStream(child.getInputStream());
ObjectOutputStream out = new ObjectOutputStream(new BufferedOutputStream(gos,48000));
ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(gis,48000));

out.writeObject( passRequest( obj ) );
out.flush();
gos.finish();
String sDate, eDate;

do{ 
  gis = new GZIPInputStream(child.getInputStream()); 
  in = new ObjectInputStream(new BufferedInputStream(gis,48000));
  obj=in.readObject();

  Vector<String> dates = (Vector<String>) ((CRequest) obj)
  .getInfo();
  String start = dates.get(0);
  String end = dates.get(1);  
  SimpleDateFormat sdf = new SimpleDateFormat(
      "MMM dd, yyyy hh:mm:ss a"); 
  SimpleDateFormat sdf3 = new SimpleDateFormat(
      "yyyy-MM-dd HH:mm:ss");

  Date startD = null;
  Date endD = null;

  try {
    startD = sdf.parse(start);
    endD = sdf.parse(end);
  } catch (ParseException e1) {

    e1.printStackTrace();
  }
  sDate = sdf3.format(startD);
  eDate = sdf3.format(endD); 
  gos = new GZIPOutputStream(child.getOutputStream()); 
  out = new ObjectOutputStream(new BufferedOutputStream(gos,48000)); 
  out.writeObject( passRequest( obj ) ); 
  out.flush();
  gos.finish(); 
  
}while(!sDate.equals(eDate));
//client side 
sslFact = (SSLSocketFactory) SSLSocketFactory
.getDefault();
server = (SSLSocket) sslFact.createSocket(ip, port);
server.setEnabledCipherSuites(set);
server.setReceiveBufferSize(48000);
server.setSendBufferSize(48000);
          
Date currentEnd = GlobalMethods.sDate; 
Date currentStart;
long period = 1000*60*60*6; //6 hours
long endTime = GlobalMethods.eDate.getTime();

//request splitted historical time until end date is reached
//if currentStart and currentEnd are equals, so it's the last request 
while(currentEnd.getTime() < endTime){
  
  currentStart = currentEnd; 
  long nextPeriod = currentStart.getTime() + period;
  if(nextPeriod < endTime)
    currentEnd = new Date(nextPeriod);
  else
    currentEnd = new Date(endTime);

  dates.clear();
  dates.add(currentStart.toLocaleString());
  dates.add(currentEnd.toLocaleString()); 

  creq = new CRequest(Activator.cookie,
      RequestConstants.CMC_REQUEST_DATA, segment, dates,
      ip, port);  
  gos = new GZIPOutputStream(server.getOutputStream());
  out = new ObjectOutputStream(new BufferedOutputStream(gos, 48000));  
  // /* Can we actually send ourselves and then receive ourselves?*/
  out.writeObject(creq); 
  out.flush();
  gos.finish(); 
  gis = new GZIPInputStream(server.getInputStream()); 
  in = new ObjectInputStream(new BufferedInputStream(gis, 48000)); 
  /* Returning the newly modified request with results */
  final CRequest received = (CRequest) in.readObject();  

  PlatformUI.getWorkbench().getDisplay().asyncExec(
      new Runnable() {
        public void run() { 
          pref.processData((GeneralDataObj) received
              .getInfo());
        }
      }); 
}
and the server log error :

Also you must use the same ObjectOutputStream and ObjectInputStream for the life of the socket.

but how come sometimes I have this error and sometimes it works perfectly fine ?
EJP
Because of the occasional network transmission problems I discussed in the thread I referred you to.

Thanks for the thread link.. interesting description.. ;)
so is there any way to solve this issues..?
if you look at the code, basically what im trying to do is the following:
- a client connect to a server using sslsocket.
- server receive the connection and reply with the first part of the data and keep the connection open.
- then client receive the reply and request for another data using the same socket connection
- then server receive the next request and reply with the second part of the data and close the connection when the loop is finish.

what im trying to do is actually to chunk the download size. consider I need to download a 20MB of data from the server, using a single request is fine, but client have to wait for sometime until all the data is downloaded. so im trying to chunk the data into several part, and the server will send the chunk of data one by one. so the moment client receive the first part of the data, it will display it directly and at the same time will process the next data.

creating a new socket request for each chunk of data will be slow since it has to keep open and close the socket to server several times.

so in short, im trying to utilize one socket connection to do several data communication between client and server.
can you help point out what i did wrong in doing this..? or a link to any site providing example in doing this..?

Thanking you in advance for your help and sorry for the length of the post.. :)

Nothing wrong with what you're doing. There is a problem in the network somewhere.
