When uploading large files (for example, 9GB) via the file upload API the upload never succeeds. Smaller files (10KB - 500MB) are successful. We may be hitting a 2GB upload limit.

Acceptance Criteria:

Allow large file uploads, provided the disk storage is available.
Accept up to 20 GB files.
Review issues related to accepting large file sizes.

Todo: Identify a suitable test file (EJN).

Note: Ideally accept up to 50GB.

Note: The curl command line logging shows the following:
