The last time I tried to do strace, I was writing output to the target disk, which interfered with the reproduction. To remedy this, I mounted a scratch ext4 volume to write the strace data. What it shows is a rename() call returning ENOSPC. This looks like a btrfs bug which should be pushed upstream.
