I had to reboot regularly after a few days because of this problem. dbus-daemon took 100% CPU with "too many open files" (strace) and dbus communication came to a halt.
Like Warren Jones mentioned in https://bugs.kde.org/show_bug.cgi?id=261180#c4 dbus-daemon as well as "kpackagekitsmarticon" have lots of open sockets and it helps to: killall kpackagekitsmarticon KDE recovered - no need to reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779849 Title: dbus-daemon consumes 100% CPU -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
