Red Hat Bugzilla – Bug 189610
CPU @ 100% with multiple running bonobo-activation-server
Last modified: 2008-03-20 09:56:36 EDT
Description of problem: There are five bonobo-activation-server running. The top four running system processare are bonobo-activation-server which is pushing the CPU to 100% and system load to plus four. Version-Release number of selected component (if applicable): 2.6.16-1.2080_FC5 libbonobo-2.14.0-1 How reproducible: This problemm exists on all five of our FC5 systems. Steps to Reproduce: 1. gconftool-2 --type boolean --set /desktop/gnome/interface/accessibility true 2. logout then login 3. top Actual results: I get 5 running bonobo-activation-server processes with four being the top system hogs taking 100% of the CPU. Expected results: I expected only one bonbo-activation-server process running and taking very little system CPU time. Additional info: /var/log/messages has several bluetooth related bonobo access errors.

Try removing bluez-pin, bluez-utils, and bluez-libs
Whilst the work on bug 163132 removes the b-a-s several instances problem still having a11y enabled and bluez-pin makes you use about 50% of your CPU which is bad. There must be something wrong with bluez-pin. Here is what I have found. When you enable a11y and start the gnome-session your CPU usage goes up to 100% and memory usage is also very high and you have 3 instances of bonobo-activation-server. One is nicely sleeping but the two others are active and using CPU. If you start gnopernicus or lsr you will get MORE than 3 instances of b-a-s. If you leave your computer on for a night, next day you will find it's unusable and have to reboot it. With my patch you found out that CPU usage goes down to 50%, memory also goes down and you only have one instance of b-a-s. Still I didn't like CPU to be @ 50% so I started looking and found out that my FC5 installation had something called bluez-pin (something related to blue tooth) running and that guy was eating the 50% of the CPU. If i killed it then I was down to a fine 0-5% CPU usage. So I decided to get rid of that bluez thing but gnome-session inssited that I needed it so I unstalled it. Now my memory and CPU usage is normal. So I decided to go back a few steps and try to see what happens without my patch and without that bluez being loaded. I found out that only one b-a-s instance was running (as expected) and CPU usage was almost as good as with my patch. So, there is something in combining a11y with bluez. Prolly a bug should be added somewhere.
Do you have a 2-cpu computer?
Yes I have. [ariel@paula rpm-src]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz ..... processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz
I have 1 CPU and bonobo-activation-server eats 100% of cpu after reboot (when I start nautilus). Bonobo is totally buggy component (unusable gnome desktop for normal user).
are you guys still seeing this with the packages sitting in -testing ?
We have removed bluez-pin, bluez-utils, and bluez-libs from our systems. We will try again on FC6.
Hi, We no longer support Fedora Core 5 and I am currently trying to get my open bug count down to a more manageable state. I'm going to close this bug as WONTFIX. If this issue is still a concern for you, would you mind trying to reproduce on a supported version of Fedora and reopening? (this is a mass message)
The problem of multiple bonobo-activation-server when a11y was enabled was fixed as a good side efect of this bug: http://bugzilla.gnome.org/show_bug.cgi?id=163132
Excellent.
