I wrote a small app to test (which i will paste the main below) but so
the problem seems to be machine specific.
I have a windows 2003x64 VM (vmware) with 4 GB ram and when I run this
program it will consistently fail at 31MB of data.
On any non virtual machine I have run it on it will go past that 31MB
limit
Anyone have any ideas?
Thanks
