Can you please check whether it was the D-Bus system bus or the D-Bus
session bus? When you run `ps axu | grep dbus-daemon` you should get
something like this:

thoenig@nouse:~> ps axu |grep dbus-daemon
100 3122 0.0 0.2 5160 2636 ? Ss Dec05 0:33 /usr/bin/dbus-daemon --system
thoenig 5050 0.0 0.0 3772 872 ? Ss Dec05 0:00 /usr/bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session

Then run `top` to identify which of the processes is the CPU hog.

This all sounds very scary and I've never seen it before. It might be
that an application misbehaves and causes a lot of traffic on the D-Bus
daemon process. This in return may cause the D-Bus daemon to suck all
of the CPU cycles.

In any way, please file a bug against SUSE Linux 10.1 on [1] in order to
solve this issue.

Thanks,

Timo
