The box freezes, is that what you mean?
Or is it just impossible to create extra files.

How many images did you actually get onto the volume? It might have run
out of inodes. The default is to allow a maximum of 25 percent of the
diskspace.
if you could run xfs_info that would be helpful.
(provided in the xfsprogs rpm or in the cmd branch of the CVS tree)

It should work.
You can adjust the maximum amount of inode space using xfs_growfs I think.
Otherwise you can always specify it at mkfs.xfs time how much percent is
the limit.
