Hello Marwin,

What was the command line of ./configure invocation before the build and
what is the resulting content of, say, ./Makeconfig and
libsrc/Dk/Dkconfig.h ?

Best Regards,

by the way, if i take out the first line ?s1 ?p1 ?o1
the results will be returned very fast. When I keep that line the server eventually hangs.

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

Hi,

I am doing a query on dbpedia
the virtuoso server is hanging on futex_wait according
to
system monitor. Here is the strace too:

:~/DataBases/dbpedia$ strace -p 6118
Process 6118 attached - interrupt to quit
futex(0x241d424, 0x80 /* FUTEX_??? */, 793


Shutdown fails as well.
This seems serious. Is it known? Give me the fix, if
not
where would you like me to report a bug?

Thanks!
Marv

PS. 8 gigs ram on
64 bit ubuntu 8.10 on 64 bit dual core amd athlon
kernel 2.6.27-7
