I recently realized that every time I lunch emacs, after a minute, a strange buffer appear in buffers list that is linked to an emacs process, infact it also appear in system's process list: enter image description here

When I try to close emacs C-x C-c in mini buffer appears a message that ask me if I'm sure to kill that buffer that has a running process.

That buffer contains only this line:

Lisp expression: Git variable `github.user' is unset.  Set to: 

and I don't know how to interact with this buffer

If I kill the buffer without closing emacs, this message appear in mini buffer:

error in process sentinel: Selecting deleted buffer

Can you tell me a way to prevent the creation of this buffer/process?

    Do you see the same problem when you start Emacs with emacs -Q (no init file)? If not, bisect your init file to find the culprit. – Drew Jan 5 at 22:30
  • You should try to figure out what's going on firstly. Emacs has such behavior because of something you ask Emacs to do. By the way, "Git variable `github.user' is unset." is from ghub.el, and ghub.el is a github library, so maybe you asked Emacs to access github via some packages which requires ghub.el. – xuchunyang Jan 6 at 4:08
  • I don't know this for sure, but I would guess: async.el judging by the name does some async stuff, so it may be running a separate Emacs process for this. You must have installed some package for interacting with GitHub that uses async library, but didn't configure how that package logs into GitHub or something similar. – wvxvw Jan 6 at 6:42
  • I cleaned the .emacs.d folder and after I restored only known files and now the problem seems finally resolved. Thanks to all – MeschiX Jan 7 at 15:13
