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

[John Charonko]

kaloyan and kcstrom -

It's possible you are experiencing a different dbus bug from those with
the too many open files problem.  For me, the update to Kubuntu 11.10
resolved the problem.  It appears the kdelibs patch that was included in
that release fixed it, as expected.  I'm just frustrated it took so
long, but at least it's done now.

What release are you on?

Have you tried to look at dbus-monitor? Maybe you can see if a
particular program is behaving badly.

In the case of the kdelibs problem I was having, dbus-monitor was
completely silent, like it was locked up or unable to respond, probably
because it was waiting to open a new file.
