I checked the *scratch* buffer status, indeed the `auto-save-mode` and
`auto-save-visited-mode` are enabled. And the value of variable
`buffer-auto-save-file-name` is: "/Users/stardiviner/#%2Ascratch%2A#lfiW0Q#"

Indeed found the problem! Hahaha, Thanks, Eli.

How to get around this problem? I disabled `auto-save-mode` now in my Emacs 
config now.

But I use git blame check out the `auto-save-mode` config lines, I
enabled it long time ago, but have not happened this problem before.

Anyway, problem solved now. Thanks a lot! Guys
