I’ve been having an issue with uploading files larger than 2 GiB to Box. No matter the size of the file, the upload fails when it hits 2 GiB. The output of -vv is below.

The command used is pretty simple: rclone -vv sync /media/freenas/test freenas-box:/test. The backend is a Freenas NFS share mounted to /media/freenas. When I upload large files without multipart (using --min-size 2G --box-upload-cutoff 15G) it works fine. Some people were having issues with Box and multipart upload (#2054), but the error seems different. To be safe, I tried increasing --low-level-retries to 100 but it didn’t help.
Also something to note is that I ran this on a Raspberry Pi, and I’m pretty sure that’s 32-bit (armv71). I’m using rclone v1.42. Thanks in advance for your help!
Edit: I ran the same thing on a Windows machine and it worked fine. Seems to be specific to the device/architecture.
