Hi,

I was searching for a mail in Kontact and virtuoso-t started to use the cpu heavily and continiuos to do so. I looked at https://kdeatopensuse.wordpress.com/2011/11/09/debugging-nepomukvirtuosos-cpu-usage/ to find the culprint and found a query that did not disapper, it looks like this

Code: Select all

:~$ qdbus org.kde.nepomuk.services.nepomukqueryservice /nepomukqueryservice/query1 queryString
qdbus org.kde.nepomuk.services.nepomukqueryservice /nepomukqueryservice/query1 queryString
select distinct ?r ?reqProp1 (bif:concat(bif:search_excerpt(bif:vector('card'), ?v1),bif:search_excerpt(bif:vector('card'), ?v3),bif:search_excerpt(bif:vector('Cytometry'), ?v4))) as ?_n_f_t_m_ex_ where { { ?r <http://akonadi-project.org/ontologies/aneo#akonadiItemId> ?reqProp1 . { ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#plainTextMessageContent> ?v1 . FILTER(bif:contains(?v1, "'card'")) . } UNION { ?r <http://www.semanticdesktop.org/ontologies/2007/01/19/nie#isPartOf> ?v2 . ?v2 <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#plainTextMessageContent> ?v3 . FILTER(bif:contains(?v3, "'card'")) . } . FILTER NOT EXISTS { ?r <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#messageSubject> ?v4 . FILTER(bif:contains(?v4, "'Cytometry'")) . } . ?r a <http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#Email> . FILTER EXISTS { ?r a [ <http://www.semanticdesktop.org/ontologies/2007/08/15/nao#userVisible> "true"^^<http://www.w3.org/2001/XMLSchema#boolean> ] . } . } . }


Even after a reboot Kontact stays very unresponsive and as soon as it is a very active virtuoso-t pops up in top and stays there. Is there any way to get rid of the query?

edit: forgot this is with kde 4.9.3 under kubuntu 12.10

It is a known issue in queries. The fix will be present in the next major version of KDEPIM (4.10), and the Nepomuk developers will likely backport it for 4.9.4.

That is great to hear, thanks for the info and of course to whoever fixed that bug.

Oh and to end the query, if I would have just hit tab for autocompletion once again I would have seen the way to end the query. The complete line was

Code: Select all

qdbus org.kde.nepomuk.services.nepomukqueryservice /nepomukqueryservice/query1 close

and after a while (and a restart of kontact) virtuoso-t vanished from the list of processes chewing on cpu time.
