Something is pegging my CPU at 99%. Top shows dbus-daemon.by "clean install" do you mean you have not added the update
When this happens no other programs will launch. Existing
running programs are very sluggish. How can I determine what
is causing this? It occurs every few days. Running 11.4 KDE
on a clean install. Switching to runelvel 3 does not cure the
issue, only a reboot. This does not make sense to me.
repo and performed an update?
No, I mean that I installed originally to a new partition, not an
upgrade of an earlier version of openSuse. I have done all suggested
security updates. I am running an onboard nvidia 6200 chip with default
What does top show you when the CPU is pegged at 99%?
Top shows dbus-daemon using 90+ % CPU. I don't know what is causing that.
running 'dbus-monitor' should give you a clue what is using dbus so much
On a different machine I just had the same issue. That one is a quad core i5. dbus-daemon was using 100% cpu cycles on one of the cores. But no un-running programs would start, i.e. Thunderbird, or even a konsole window. I closed those windows that were running and dbus-daemon stopped immediately after I closed a Dolphin window (opened to Home). Now it gets a little more interesting. A short while after that, say about 30 seconds or so, dbus-daemon started taking up 100% cpu on a different core. Still no programs would open, so I switched to console 1 (ctl-alt-F1) and ran dbus-monitor. That reported that dbus-daemon did not start correctly giving an error X11 dbus-daemon failed to load. But top showed it utilizing 100% cpu. (BTW this machine is also running openSuse 11.4 with KDE).
Would appreciate any ideas. Thanks.
