Re: virtuoso taking too much cpu time

For the last month or so I am having the problem that virtuoso-t is
hogging the cpu even when file and email indexing are suspended.
My main issue was that mail reading under kmail got really slow and while
searching on the net for it I did not got any clue of how to see what
virtuoso was doing and how to fix this issue.
Today I deactivated desktop search in system settings and now reading
email got fast (and usable) again.
I am writing this message hoping that someone has an hint how to fix/debug
this.
Mine on my relatively fresh f20 install started doing that too... knowing
it's contents were relatively small/nil, I just stopped nepomuk, rm -rf
~/.kde/share/apps/nepomuk/ , started nepomuk fresh
Before clearing it, I did see a *lot* of errors logged to
.kde/share/apps/nepomuk/repository/main/data/virtuosobackend/soprano-
virtuoso.log, repeating this a bunch:
