I'll have to get back to you on version numbers but I didn't test the 6GB file on other servers. I actually tested a much smaller file on another server and it seemed to work. Originally I was testing an 18 MB file and this was failing with web sharing but succeeding on other servers. I had a co-worker try this 18 MB file out on his web sharing machine and his seemed to work. At that point I swapped it out for a 6 GB file and then it happened again.
