Hi,
We have further investigated this here and have tested with multiple 4gb+ files and couldn't reproduce the issue. We can only think of this as an issue with the file itself, or a specific combination of the file, and the way we build up the post-data to send it to the service. A couple of questions:
- Did you always test with the same file?
- Is it possible to send us the file, so we can investigate this here?
