filezilla, error while writing failure

Question

I'm transferring a very large (35GB) file through SFTP and FileZilla.

Now the transfer is 59.7% done, but I keep getting this error, and it hasn't changed that number for hours.

Error:     File transfer failed after transferring 1,048,576 bytes in 10 seconds
Status:    Starting upload of C:\Files\static.sql.gz
Status:    Retrieving directory listing...
Command:   ls
Status:    Listing directory /var/www/vhosts/site/httpdocs
Command:   reput "C:\Files\static.sql.gz" "static.sql.gz"
Status:    reput: restarting at file position 20450758656
Status:    local:C:\Files\static.sql.gz => remote:/var/www/vhosts/site/httpdocs/static.sql.gz
Error:     error while writing: failure

Why do I keep getting this error?
