Possibly, if the file is > 2 GB, you might be running into a limitation 
of the shell itself. I think most shells nowadays handle this fine, but 
there are still a lot of semi-modern tcsh shells limited to 2 GB still. 
Something like cpio could bypass cp and at least rule out that cp itself 
is at fault, e.g.:
   find /SomeSource -print -xdev | cpio -pdm SomeDestination

(make sure find can see it first...the above should be adjusted, I use 
it for drive mirroring)
