Problem in Image uploading through a view -- URGENT

Question

Hii Experts,
I am facing very strange problem while uploading a image file (.JPG file) thru a web dynpro view.
I am accepting a image file from view and uploading it to a ftp server.
There are two abnormal results I have observed. It does NOT  happen for every image upload. But it has been observed to happen during peak Internet hrs. (image size can range from 1MB to 7-8 MBs)
When 'Upload' button is clicked, one of the following thing happens:-
1.  After taking loooong time (processing circle rotates), browser screen goes totally blank. That is, browser goes into state as if no page is opened (white screen)
2. After taking loooong time, empty form re-appears. ( ie the view in which i had submitted data and pressed 'Upload')
I have tried tracing errors in default trace. but no error or exception is displayed !!!
Following is the code i'm using for uploading file. ==>
try {
URL myUrl = new URL("ftp://<some address>");
FtpURLConnection myConnection = new FtpURLConnection(myUrl);
myConnection.connect();
OutputStream out = myConnection.getOutputStream();
out.write(wdContext.currentPhotosElement().getPhoto1());
out.close();
myConnection.close();
} catch (Exception e) {
System.err.println("\n\n$$$$$$$$$$$$$Exception in image upload $$$$$$$$$$$$$\n\n");
e.printStackTrace();
Please help me as this system is live and lot of users are complaining as they are not able to upload their images..
Awaiting for reply ..
regards,
Amey
