We do support >4 GiB.

What happens if you bypass Nextcloud and use a standard SFTP or FTP client to upload to the same external storage?

[strangmann]

If I start the data transfer without Nextcloud as an interface, the file is transferred without any problems. I just tried it with SFTP, it probably works the same with FTPs.
Can't you recreate my scenario?
In my environment, an average of 80MB/s is possible between the Nextcloud server and the SFTP server, at least when I start the data transfer locally on the Nextcloud server.

Was this test with a >4 GiB file?

The reason I'm asking is because 4 GiB is not a random number. It's is a fairly specific number. It tends indicate a problem related to using a 32-bit OS or a filesystem that doesn't support >4 GiB files (like FAT32).

The spot where it's failing is on the put() to the remote. What do the logs of your SFTP server indicate happened?
