I am using 9.6.7-7 (adapted from the Debian 12 distributed version) on both
Debian 12/ARM64 (Raspberry Pi 5) and Debian 12/AMD64 (a VPS), with a max part
size of 1G and a max vol size of 5G.  This works well for me.

It would not supprize me if the Amazon S3 API has some upper limit on file
size.  I know that Amazon Glazier has a limit on the transfer size for large
files (they must be uploaded in parts).
