OK, so 550GB data and 4.5M files.

It has written a huge object and now rejects to read it, see:

What we are wondering about:

You don't have that many files, it is just 4.5 million files.
Also they are not that big as the total size is just 550GB.

Also, you said you have a lot of hardlinks (which borg stores as
chunkless item that keeps a reference to a "master item" with the chunks
list - but it will store ACLs and xattrs for the hardlink item separately).

So why are your metadata items that big? Do you have a lot of ACLs or
xattrs?
