Do your filesystem, OS, perl, and apache installs support files larger than 2GB? 2**32 == 4294967296 (4GB), and the signed version of that value is 2GB, you are limited to 2GB unless all of the above use file offsets of greater than 2**32. Search for "largefile".

Update: Specifically, run perl -V | grep -i largefile and see what it says. Mine has uselargefiles=define and -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' in the output. I seem to remember Apache having the same type of configuration, I know that my filesystem has to have a flag set to support large files, and operating systems have not always supported files larger than 2**31-1.
