Rsync doesn't appear to handle large files

[Buwalda, Mark W]

I just started using rsync version 2.5.6 on sun solaris 8.
In trying to mirror a large ufs filesystem, I've noticed that
Rsync does not copy large files, specifically any file greater 
Than 2 GB.  
All other files in the filesystem were mirrored properly.

Is this a bug/limitation of rsync on solaris, or is there 
A workaround for this ?

Thanks.
