problem with mkisofs

I am facing the problem while making the image with mkisofs command. I am using the Dual Layer DVD (9.4GB), Please have a look the output.

# mkisofs -r -o /tmp/backup-disk1.iso /home/dwadmin/backup/backup-20080311.tar.gz
INFO: UTF-8 character encoding detected by locale settings.
Assuming UTF-8 encoded filenames on source filesystem,
use -input-charset to override.
mkisofs: Value too large for defined data type. File /home/dwadmin/backup/backup-20080311.tar.gz is too large - ignoring
Total translation table size: 0
Total rockridge attributes bytes: 169
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 0
175 extents written (0 MB)

Can any body help me to sort out the problem.

Thanks.
