In the server's syslog, it's

That sounds similar to the problem that I’ve been having since March
that I can’t seem to sort out. I’m using rsync backups, but trying
tar backups has run into the same issue. My backups will hang,
seemingly indefinitely—I’ve had a backup sit unmoving for 7 days
before. Sometimes, killing that backup and running a new full will
give me a reprieve. But I’ve not been able to find or fix the
underlying cause to this point.

Well, yes. rsync 3.1.x has a bug which might be directly affecting
your transfer, and sounds related to your use case:

If this is the case, either upgrading (or downgrading) should take
care of the issue.
It's not a process hanging, just plain crashing (which may come from
the
same bug or not). Since it's rsync_bpc that goes over the cliff, it may
not be related to an rsync bug.
A crash like that is probably not the same bug, sorry for
misunderstanding. For the record, that bug manifests itself only as an
apparent hang (though rsync does seem to spend its time re-reading the
same files.)
