I am going a cpanel back of an account and having it sent automatically via FTP to a remote box. The issue I am having is that the file is being reported as impossibly large.

-rwxr-xr-x 1 root root 18446744072971976146 Mar 27 02:53 auto.tar.gz

This account is actually about 5 gig in size.

any clue what would make the file size to be out of wack?
