title: Linux - What happens to user's running processes when its password is changed?
body: <p>On one server I have an application running as a non-root linux user.
  I forgot its password, so I was about to change it using root priviledges, but then I wondered if that could harm the application running with that user.</p>
  <p>I looked online but I didn't find any answers to this. Does anything happens to the user's running processes when the user's password is changed?</p>
