    Red face OutOfMemoryError caused in a loop at new BufferedImage

    Have increase the memory size but that only increase the images send and received about x3, so the really solution is if there is a way to manually de allocate the memory without the gc or really force gc to do so…if that a no, could there be some modification that could FIX this???
    thanks

    //server
            int number=0;
                try {
     
                    while(true){
                         ImageIcon imageIcon = (ImageIcon) ObjectInputStream.readObject();
                         System.out.println("New image recieved");
                         BufferedImage bim =new BufferedImage(imgIcon.getIconWidth(), imgIcon.getIconHeight(), BufferedImage.TYPE_INT_RGB);
                         ImageIO.write(bim, "JPG", new File("image"+ number++ +".jpg");
    				Runtime runtime= Runtime.getRuntime();
    				runtime.gc();			//doesnt work
    		}
    	}cartch(IOException ex){
    //
    	}
     
    //client
    	screenDim=Toolkit.getDefaultToolkit().getScreenSize();
            scrRect=new Rectangle(screenDim);
     
            while(true){
                bufrdImage=robot.createScreenCapture(Toolkit.getDefaultToolkit().getScreenSize());
                imgIcon=new ImageIcon(bufrdImage);
     
                try {
                    client.oos.writeObject(imgIcon);
                    System.out.println("image Sent");
                } catch (Exception e) {
                }
                bufrdImage = null;
                imgIcon = null;
    				Runtime runtime= Runtime.getRuntime();
    				runtime.gc();		//to de allocate bufrdImage, imgIcon but doesnt work
                try{
                    Thread.sleep(1000);
                }catch(InterruptedException e){
                }
            }

    any idea?

    Default Re: OutOfMemoryError caused in a loop at new BufferedImage

    Which is throwing the exception, client or server (or both)? If you are getting an OutOfMemoryException I doubt its the garbage collectors fault.
