What nginx version? The latest changelog (0.5.19) includes this:

    *) Bugfix: the files more than 2G could not be transferred using           
       sendfile and limit_rate on 64-bit platforms.                            

    *) Bugfix: the files more than 2G could not be transferred using           
       sendfile on 64-bit Linux. 

Possibly related? If you are running 0.5.19, I don't have a fix but I do have a
workaround. Put "sendfile off;" in your config, and nginx will use a different
system call to send the data.
