[gentoo-user] nepomuk/virtuoso using 100% cpu
Since the upgrade to kde-4.6.3, nepomuk and/or virtuoso insists on giving my
cpu a stress workout. usage is pegged at 100% and .xession-errors is full of
junk like this:
/usr/bin/nepomukservicestub(13816) Soprano: SQLExecDirect failed on query
'sparql select distinct ?r ?reqProp1 where { { ?r
http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#to ?v2 . ?v2
http://www.semanticdesktop.org/ontologies/2007/03/22/nco#hasEmailAddress ?v3
. ?v3 http://www.semanticdesktop.org/ontologies/2007/03/22/nc' (iODBC Error:
[OpenLink][Virtuoso iODBC Driver][Virtuoso Server]SQ074: Line 1: SP030: SPARQL
compiler, line 1: syntax error at '' before 'http:' at '' immediately before
end of statement)
and this:
/usr/bin/nepomukservicestub(13066) Soprano: SQLExecDirect failed on query
'sparql uboku' (iODBC Error: [OpenLink][Virtuoso iODBC Driver][Virtuoso
Server]SQ074: Line 1: SP030: SPARQL compiler, line 1: syntax error at
'uboku')
kdepim is 4.4.11.1.
Everything else is at latest unstable.
I remember having to deal with this once before with an ill-fated experiment
at using kdepm-4.5.95, but cannot for the life of me find what I did to fix
it.
Anyone have some pointers?

It says that if If virtuoso is killed while nepomuk indexes the indexing does
not stop and nepomuk spams the .xsession-errors file.
Is your virtuoso running?
Have you tried running kdedebug --off area to see if the error logging stop?
I am just updating kde on an old machine (only runs sqlite instead of mysql)
and hope I will not have such problems - or worse!

That has a familiar ring to it. Not quite the full answer though, I'm hoping
that will come after a restful night's sleep.
It says that if If virtuoso is killed while nepomuk indexes the indexing
does not stop and nepomuk spams the .xsession-errors file.
Is your virtuoso running?
Yes. I'd been having problems with this cpu usage most of the day, but I could
live with it - any app that needed to do stuff would receive cpu time with a
short latency lag. At the end of the work day, I suspended as normal and
looked closer into it at home. I can't swear to it, but I'm certain virtuoso
was running. It definitely was running (and the problem as a whole got much
worse) after logging out of kde and logging back in.
Oddly enough, manually killing kontact and everything relating to akonadi,
nepomuk and virtuoso then restarting them made the issue go away.
Next step I suppose is to log out and in again and see what gives then.
Have you tried running kdedebug --off area to see if the error logging
stop?
I don't have such an app as kdedebug. What package provides it?

mysql) and hope I will not have such problems - or worse!

Yes, apologies - meant to write kdebugdialog, but was getting too late last night for the synapses to reach the keyboard accurately! o_O -- Regards, Mick signature.asc Description: This is a digitally signed message part.
