Please also note that my above post (providing the backtrace and strace) was a little overzealous -- in my effort to get a useful backtrace (with the built debug-packages) I have been unable to preproduce the described situation since the bugreport, but when I noticed the mentioned 100% CPU activity today I thought that the bug went back -- checked via ps to see if the duplicate gconfd-2 is running and then followed the steps from the wiki to obtain a backtrace of gconfd2. But when I just checked which process has 100% CPU usage it turned out to be... ekiga, NOT gconfd2! But I hope the info was useful after all. -- gconfd-2 doesn't stop for previous user logged into GNOME https://launchpad.net/bugs/85521 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

The "relict" process is /usr/lib/libgconf2-4/gconfd-2 that runs for the previously logged-in user, and I don't know what it's doing but it eats all the CPU activity (100%). -- gconfd-2 doesn't stop for previous user logged into GNOME https://launchpad.net/bugs/85521 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 85521] Re: gconfd-2 doesn't stop for previous user logged into GNOME
Since my bugreport I hadn't experienced the unusually high CPU usage for gconfd-2, but I noticed that the respective process for previously logged user(s) still persists. I don't know if this behaviour is normal or not, but I assume that the high CPU usage comes when the "relict" process has experienced segmentation fault.

Building the debug packages turned out to be much easier than I thought, but after installing them the update-manager wants to update these -- I suppose that I don't want to do that unless I've finished using the debug version.

Thank you for the work on that. That's normal that the CPU usage stops when gdb attach the process because it stops it. The backtrace looks like a problem, it lacks details to be useful though.

Well, I have tried to run the described steps (for an already running program) with sudo and here the output is attached. It is interesting that after issuing "attach 5771" the CPU usage dropped to normal levels (2-3%), but when I said "quit" at the gdb prompt and "exited anyway", the CPU was again at 100% use by the same process. ** Attachment added: "gconfd-2-gdb.log" http://librarian.launchpad.net/6448852/gdb-gconfd-2.txt -- gconfd-2 doesn't stop for previous user logged into GNOME https://launchpad.net/bugs/85521 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I'm glad that I still haven't rebooted since then to get rid of the annoying situation and the observed anomaly still eats almost all of my CPU cycles, so here is the requested info. First of all, I am unable to do successfully "(gdb) attach " as described in the wiki -- I get "no permission". Is it safe to run the gdb commands from the wiki as root?
