[Virtuoso-users] Virtuoso Server Still Hangs Sleeping on Futex_Wait

[Marvin Lugair]

Hello,
I am still having this problem with the virtuoso server on any query of 
significance on the latest debpedia. I have 146 million triples of the core 
dbpedia 3.2 loaded on my 8 gig machine. I tried the suggestion you guys sent me 
including recompiling with the pthreads flag. Nothing works.


Here is my latest query:

sparql  SELECT ?label1, count(*)
                WHERE {
                        ?s1 ?p1 ?o1 .
                        ?s1 <http://www.w3.org/2000/01/rdf-schema#label> 
?label1 .
                        FILTER(lang(?label1) = "en").
        }
;



Thanks!
Marv
