Version: (using KDE 4.2.4) Actually this happens with KDE 4.3beta1, but selecting that product in the wizard does not work :( It would be great if nepomukstorage could "nice" itself to 19 or so to give it lower priority and make it easier to work during initial indexing. See this mailing list thread: http://article.gmane.org/gmane.comp.kde.nepomuk/396
This is no solution. We are now using Virtuoso which is spawned in another process. Thus, the storage service does not do much anymore anyway. Also any high usage of the storage needs to be resolved on the client side, i.e. less requests.
