Description Bill Metzenthen 2011-08-04 12:42:46 UTC
Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

The session bus dbus-daemon consumes 100% of one core starting about a week after a fresh boot.

There is a suggestion (http://us.generation-nt.com/answer/bug-630002-dbus-dbus-daemon-consumes-40-cpu-amd64-help-203742362.html) that this may be related to " a KDE process that leaks D-Bus connections".

/proc/ID/fd shows that dbus-daemon has 1024 file descriptors, most of them sockets.

This is on Kubuntu 11.04

KDE applications such as kmail, knode, etc become unusable when dbus-daemon gets to this state.

Which application(s) are likely to be causing the problem?  Is there any way other than re-booting to get dbus-daemon to resume functioning correctly?

Reproducible: Always

Steps to Reproduce:
Just run KDE for a few days.

Actual Results:  
dbus-daemon stops some KDE applications from functioning correctly

Expected Results:  
All applications should function as normal

Can you check if this is fixed in KDE 4.7? It is probably caused by Software Update Notification tools, which are provided by your distribution. See bug 261180.

I will check with 4.7, but first I will gather a little more data with the current installation.  At the moment I have an uptime of one and a half days and the number of descriptors in use by dbus-daemon has peaked at less than 100.

Because it takes several days before dbus-daemon finally stops the KDE processes from working properly, it could be a couple of weeks before I say whether or not 4.7 makes a difference.
