[Bug 680444] Re: dbus-daemon eats 100% cpu and is not responsive

[kaloyan]

dbus-daemon goes crazy for me as well (Ubuntu 10.11) and I don't see
anything unreasonable in the number of open files:

115 2844 //bin/dbus-daemon--fork--print-pid5--print-address7--session
96 3566 gnome-terminal
71 3165 /usr/lib/firefox-6.0/firefox-bin
36 2901 /usr/bin/pulseaudio--start--log-target=syslog
32 2906 compiz
28 2792 gnome-session--session=ubuntu
27 2915 nautilus-n
27 2867 /usr/lib/gnome-settings-daemon/gnome-settings-daemon
24 3101 update-notifier
24 3084 /usr/bin/python/usr/lib/ubuntuone-client/ubuntuone-syncdaemon

It is making my computer near unusable (or at least extremely annoying
to use)
