I did create two bugreports:
https://bugs.kde.org/show_bug.cgi?id=317122
(KMail went up to 2GB of ram)
https://bugs.kde.org/show_bug.cgi?id=317120
(Korgac going 800mb+ within seconds after starting)

I also have been having virtuoso eat 100% cpu for about 4 days straight now. 
Vishesh, if you have a command I should run to find out why it is doing 
that, maybe we can find out what is wrong...

I did run:
qdbus org.kde.nepomuk.services.nepomukqueryservice

Which gave one active query:
/nepomukqueryservice/query1

So I ran:
qdbus org.kde.nepomuk.services.nepomukqueryservice 
/nepomukqueryservice/query1 queryString

The output of which was:

select distinct ?r ?reqProp1 where { { ?r <http://akonadi-project.org/ontologies/aneo#akonadiItemId> ?reqProp1 . ?r 
<http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#isRead>
