[opensuse] dbus-daemon 100% CPU. Constant disk access.
I have suddenly started to see very strange things in my openSuse 10.1 installation on my laptop. I was up to date with updates/patches, until about a month ago, but have done no updates lately, and the only new software I installed is the Novell linux client. First problem I have is that there is a process called dbus-daemon that is taking up 100% CPU, all the time. I don't know what this process is, or if I could kill it safely, and why is it doing what it is doing. When I do kill this process, CPU time is freed, but some process is writing/reading from the hard disk constantly (i.e. the hard disk light is constantly on). How can I find out which process is accessing the hard disk?

Thanks Marius Roets
Not long ago i had some strange issues just because my harddrive (the root partition) was completly full. Please check youre drive with KDiskFree (Alt+F2 kdf), or with df -h on a console.

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.

Yes, it is the session bus. That's actually good news ;-)
I will file the bug.
Thanks for that. Please assign the bug directly to me and I will give further instructions. Thank you, Timo -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
