I am trying to upload 2 files to one machine and another 3 files to another machine using my FTP program. In this situation we have two threads running at a time for the two machine. This threads will check a folder named outbox in a particular time interval using the QTimer for any files to be uploaded. User will continuously copy files to be uploaded into the Outbox folder at irregular time intervals. For two or three times the file uploading will complete successfully. After that the datatransfer will slow down gradually and finally it will work endless without any progress in datatransfer. For monitoring the transfer progress I have connected the dataTransferProgress Signal. I am using many pointers and Objects and also I am deleting the pointer objects after its usage. Is there any other debugging methods for memory leak in Qt4.7 Please help me. I am trying it for 2 Weeks

Thanks in advance
