Restore session freezes while restoring the db

I back up my site to a remote FTP server. While I am restoring my database backup, it freezes at the end of the process.
When I go back to restore page, it shows an error saying that there is an unfinished restoration process, but when i try to finish it, it says it could not find the file. Indeed, when I return again to restore page it does not show the backup file i wanted to restore. But the connection is successful with my FTP server. Below is the log file.

How can i fix this?
