the dependencies list for ibus. (Wish I didn't have to start a remove and say "no" to get this.)

The dmesg
For what it might be worth.

Maybe some recent update fixed part of this. I don't know what was changed in your environment. But if you mean you no longer reproduce your problem, I'd like to close this issue. I don't know what changed, either. Should I dig into the yum logs? But, as far as the bug is concerned, I didn't say I couldn't reproduce the problem, only that the most obvious symptom may have gone away. Checking just now, after another yum update this morning, the extra icon is still gone, but the zombie processes are still there after logging out. What I noted above was that they do not multiply. Only the first logout for the user seems to leave zombies behind. Hmm. Pulseaudio takes a long time to go away after logout. Well, if I log in as a different user, the IME icon does proliferat. Not the number of logins, but the number of different users that have logged in since reboot, now. Checking the logout, I get the same list of processes left over for each user. Only the ones from the first login for that user are left, but they are definitely left behind after logout. Checking, for instance, ibus-engine-xkb, while the user is logged in the second or third time, there are two, but once logged out, only the leftover from the first login (checking the PIDs). No, not fixed. OK, probably I think your session still runs dbus-daemon with a user process. If you terminate dbus-daemon, I think ibus-daemon also will be terminated. Probably I think ibus-daemon is not a zombie process. |
Created attachment 599872 [details] This is the yum info of all the packages which would be removed if ibus gets removed. Description of problem: Visually, the first sign was, after logging out and back in, there were two input method icons in the panel. More logging out and back in (independent of the user logged in as) produced more more IM icons in the panel. Using a virtual terminal to log in to a terminal session, I find these processes left over from every logout (ps wwaux | grep userX): [userX@machineY ~]$ cat leavings.text userX 12346 0.4 0.3 36420 3424 ? Sl 07:25 0:03 /usr/bin/ibus-daemon -r --xim userX 12370 0.3 2.1 115528 21420 ? S 07:25 0:02 /usr/bin/python /usr/share/ibus/ui/gtk/main.py userX 12376 0.0 0.5 33036 5936 ? Sl 07:25 0:00 /usr/libexec/ibus-x11 --kill-daemon userX 12382 0.2 1.6 57600 17288 ? S 07:25 0:01 /usr/bin/python /usr/share/ibus-anthy/engine/main.py --ibus userX 12391 0.0 0.3 22052 4044 ? Sl 07:25 0:00 /usr/libexec/ibus-engine-xkb --ibus root 12707 0.0 0.0 4588 800 tty2 S+ 07:37 0:00 grep --color=auto userX [userX@machineY ~]$ They can be killed, and the extra IM icons go away. Version-Release number of selected component (if applicable): Name : ibus Arch : i686 Version : 1.4.1 Release : 2.fc16 XFCE reports version 4.8 in the GUI widget, I'm not remembering or seeing the base package for XFCE in yum search or yum info, but the xfwm4 is as follows: Name : xfwm4 Arch : i686 Version : 4.8.3 Release : 1.fc16 How reproducible: Always happens. Steps to Reproduce: 1. Boot, log in, etc. 2. Log out. 3. Change to a virtual terminal and check for leftover processes. Leftover processes will always be present, as shown above. 4. Log back in and find one more input method icon in the panel than there was before. Actual results: Leftover processes, related input method icons repeat. Expected results: Clean logout without leftover processes, and no extra input method icons. Additional info: See attachments: The system was originally installed from a security spin image on a USB drive. I had problems with the LXDE/openbox arrangement (X11 freezing on logout, which is still an unfixed bug), so I installed XFCE. XFCE does not freeze on logout, but this problem occurs. The X11 session freezing problem (IIRC) seemed to be related to many (20 or more) leftover processes. I could kill the leftover processes and get a new X11 session, but the new session was generally unstable.
