    Default kded4 using 14GB of RAM

    I've recently updated a system to Opensuse 13.1 x86_64.
    I've noticed hard disk working too much. A free reports almost all ram used and some swap used too.
    I watch proccess memory use with top

    Code:
    Tasks: 303 total,   1 running, 301 sleeping,   0 stopped,   1 zombie

    So kded is eating almost all memory.
    why?

    It's actually using 9GB. However you should look at .xsession-errors in your home directory as well as /var/log/Xorg.0.log as to what might be causing the problem.

    Does the behaviour also happen if you create a new user account and login with that?

    why?
    A bug in some module?

    Is this reproduceable?
    Then try to disable them one by one in "Configure Desktop"->"Startup and Shutdown"->"Service Management" to see which one causes it.
    You should probably file a bug report at http://bugs.kde.org then.

    Might be caused by PulseAudio or powerdevil I'd guess, so try disabling "KMixD" and "Powermanagement" first.

    PS, might be this:
    https://bugs.kde.org/show_bug.cgi?id=271934
    So probably related to the powermanagement.

    Unfortunately the patch proposed there hasn't made it into KDE yet.
    You might want to try to update to 4.14 though, the last comment in the bug report states that it got better there...
    Although if you installed all updates you should already have the latest kdebase4-workspace.

    Something caught my eye - in your top listing, kded4 is owned by root.

    On my system 13.1/KDE 4.14.0, kded4 is owned by myusername and is using 0%cpu and 138K of memory (16GB total)

    If of any use, here is a snapshot of my top:

    Oh, right. I missed that.
    And Firefox runs as root (and as user) as well.

    kded4 should run as the logged in user normally.

    Well, kill it?
    Especially if you are not logged in as root, or are you?
    You shouldn't be.
