Filesystem size of a 64bit XFS is 9 exabytes.

Under 2.4 with a 4K page size you're limited to 16TB max file size.   
That grows to 64TB max with a 16K page size.  With a 2.6 kernel and  
CONFIG_LBD set you're looking at a max file size of 9 million TB.

I don't think your file system is the constraint.  I've had similar  
behavior when dealing with failing hardware - that would be where I'd  
start first.
