Description Antonio Martins 2006-03-14 21:33:27 UTC

My system runs LTSP for 60 users concurrently, and i have noticed that many dbus-daemon instances stays indefinitely even after logout. I am using xfce4 as the WindowManager, and the following process list has 8 users logged in, but the list comes with many more user processes:

Comment 1 Antonio Martins 2006-03-14 21:35:21 UTC

Apparently there is no major impact in having these processes.

Comment 2 Michael Gross 2006-03-15 14:49:15 UTC

Reassigning to the maintainer for a comment.

Comment 3 Timo Hoenig 2006-03-20 12:55:39 UTC

Antonio, are you fine with closing this one as you are not experiencing any impact?

Comment 4 Antonio Martins 2006-03-20 17:24:08 UTC

I have impact, as dozens of processes take time, and they increase in number indefinitely.

I have been studying it with more carefull, and i see that in the first place, only one dbus-daemon process exists. However, as i am using LTSP, and they encourage the users to just press the power button to stop the terminal, they do not always logout from X session. In that case, many processes stay open until the next login:

Once the user login again, every process recycles, except for:

bribeiro  1368     1  0 16:30 ?        00:00:00 dbus-daemon --fork --print-pid 9 --print-address 7 --session

If the user now logs out correctly, every process closes correctly except for these ones.

If you think that dbus-daemon process is acting normal, please close the bug.
Is there any chance to check for previous dbus-daemon processes when a user starts a session? in that case it would reuse the already created process of dbus-daemon, or even close this before oppening another.

Comment 7 Stefan Behlert 2006-12-01 16:53:34 UTC

As it is fixed in newer versions we'll close the bug. We will not deliver an online-update for 10.0 fro this bug, sorry.
