Description of problem: Running gnome-system-monitor shows CPU pegged at 100%, but before running gnome-system-monitor the usage was 3% or less (as show by /usr/bin/top.) While CPU is 100% used, /usr/bin/top shows ----- PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1955 jreiser 20 0 500m 22m 15m S 43.7 0.7 0:20.63 gnome-system-mo 1457 jreiser 20 0 31008 1772 828 R 36.8 0.1 0:29.93 dbus-daemon 1534 jreiser 20 0 152m 3804 2788 S 9.3 0.1 0:07.63 gvfs-gdu-volume 1548 jreiser 20 0 225m 1948 1612 S 2.7 0.1 0:02.12 gvfs-afc-volume 1551 jreiser 20 0 154m 2024 1628 S 2.3 0.1 0:01.88 gvfs-gphoto2-vo 1161 root 20 0 154m 28m 7332 S 1.7 0.9 0:21.48 Xorg 1497 jreiser 20 0 1290m 66m 29m S 1.7 2.0 0:23.24 gnome-shell 1501 jreiser 20 0 145m 6636 1944 S 1.3 0.2 0:01.03 gvfsd ----- So dbus-daemon has gotten very excited for unknown reason, and taken gnome-system-monitor along for an expensive ride.

Above strange behavior was with audio CD [CD-DA format digital audio] in DVD drive at boot. Removing audio CD (press eject button on drive) causes CPU usage to decline to 5%. Booting without audio CD in drive shows only 5% CPU usage via gnome-system-monitor. So audio CD in drive at boot, plus gnome-system-monitor, triggers strange behavior.
Inserting audio CD after boot gets the "Audio Disk" pop-up, and only 5% CPU usage (both before and during pop-up). Cancel the pop-up still shows only 5% usage.
Just found this bug report after noticing the same weird behaviour on F15 (with an audio CD in the drive at boot, high dbus-daemon CPU usage). Also, gnome-system-monitor ignores all attempts to close it. Instantly resolved both issues by removing the audio CD from the drive as noted above.
Hello, I just like to report that I experienced the exact same issue with dbus-daemon as the others who commented. As Rob experienced, gnome-system-monitor ignores all attempts to close and the issue was resolved when removing the audio disk from tray.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
