Downloading multiple files results in 4 bytes download.zip when download.zip is around 2 GB and above #12405
Description
Describe the bug
On OCIS Web, when selecting multiple files for download, the resulting download.zip file is only 4 bytes instead of the expected size (e.g., around 2 GB or more).
Steps to reproduce
- Create four dummy files of sizes 0.5 GB, 1 GB, 2 GB, and 3 GB.
- Upload them via OCIS Web.
- Downloading a single file works without issues, regardless of its size.
- Selecting multiple files for download.
- If their total size is below 2 GB, the
download.zipis created and downloads successfully. - If their total size is around or above 2 GB, the
download.zipappears to be created but results in a 4-byte file when downloaded.
- If their total size is below 2 GB, the
Expected behavior
We should be able to download multiple files regardless of the total size of download.zip.
Actual behavior
When selecting multiple files for download:
- If the total size is below 2 GB, the
download.zipdownloads correctly. - If the total size is around or above 2 GB, the
download.zipis created, but the downloaded file is only 4 bytes.
