iirc, df looks at the filesystem's free space maps, while du sums the
file sizes as listed in the directories.  I'd guess that you've got
10.6G marked as "in use" in the free space maps that isn't referenced by
any inode. 'fsck -f /var' should fix it; remember that you'll have to
unmount /var first.
