Public bug reported: I installed yesterday the 11.10 version of Kubuntu on a 2.5GHz Core2Duo laptop with 4GB RAM. The install went without any problems, but after I copied ca 200GB data (lots of plain text files -- developer machine --, and a decent amount of PDF files, (Libre|Open)Office files and a smaller amount of music and image files) to my home directory, the KDE desktop becomes literally unusable maybe 20 or 30 seconds after starting a KDE session.
When I logged in via ssh from another machine and invoked "top" before starting the KDE session, it turned out that four or five akonadi processes consumed between 500MB and over 1 GB each. Well, these are the last values I was able to see: soon after, top stopped to refresh its display; typing "q" (for a subsequent "sudo halt") had no effects. OK, I did not wait for hours for a response from the SSH shell, but gave up after two or three minutes and hit the power button, assuming that the memory consumption exploded further and that there was no point to wait for hours that something visible happens. "top" did not display the full program names; it were akonadi_nepomuk_whatever and akonadi_mail_something (not 100% sure about the latter though). This is not a new issue (I had similar problems with older kubuntu versions, and it is telling that Google shows a few links "how to disable nepomuk in akonadi" on the first result page for the search term "akonadi nepomuk"), but ISTM that there is no Ubuntu bug for this issue, so I'm filing this bug. I think these resource hogs should be disabled by default. I see the point to have these so-called "Semantic Desktop Ontologies" at hand -- but there is a risk that "ontology", defined in http://en.wikipedia.org/wiki/Ontology as "the philosophical study of the nature of being, existence, or reality as such, as well as the basic categories of being and their relations", may mean in practise that a computer is too busy introspecting itself to serve the user of the machine... ** Affects: akonadi (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/927195 Title: akonadi related processes can make the KDE desktop unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/akonadi/+bug/927195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
