Unity daemon processes left after logout

[Øyvind Stegard]

Certain Unity service processes (lenses, daemons) are not killed after logging out of a session.

Steps to reproduce:
1. Create fresh standard test user.
2. Log in, use dash at least once (search for something), log out. Repeat a few times.
3. Finally logout, then hit Ctrl+Alt+1 to enter VC.
4. $ ps -u TESTUSER -f

Observe that many of the same processes have accumulated from each login/logout cycle. They are not properly ended/killed on session exit.

Example ps output after having completed the above procedure:
$ ps -u ut -f

ut 28456 1 0 20:30 ? 00:00:00 /usr/lib/x86_64-linux-gnu/unity-music-daemon

There are multiple stale instances of unity-files-daemon, unity-shopping-daemon, unity-applications-daemon and unity-music-daemon. (There are also gvfsd-trash processes which are not ended properly, but that's for another bug report.)

These processes looks truly stale and never seem to time out or get reused if the same user logs back in.

[Øyvind Stegard (oyvindstegard)]

Yes, this is most likely a dupe of bug 1072508, thanks Isaac. I'll mark as such when Launchpad will let me. Currently it times out.

[Øyvind Stegard (oyvindstegard)]

Something seems to be wrong with Launchpad, as timeout always occurs when trying to set duplicate status.
