Summary: Possible memory corruption when file > RAM

I've been having issues with file corruption and I've simplified the issue down to the following:

create a 1G file: dd if=/dev/urandom of=1G bs=1G count=1
md5sum the file twice and the results will be different.

I've tested this on ext2, ext3, backing device lvm,qcow2,raw

If I change the RAM to 2G, I can then correctly md5sum the original file, however if I create a new file that's 2G the issue reappears.

The only time the test has not failed was for the first few tests after the odd reboot.
