[Virtuoso-users] execution time error when running SPARQL query on DBPEDIA endpoint

[Lorenz]

Hello,

when i'm executing the query below on the DBPEDIA endpoint 
http://dbpedia.org/sparql, i get an error according to a negative 
execution time.

Error message:

42000 Error The estimated execution time -742267904 (sec) exceeds the limit of 
1200 (sec).
in
signal:(BIF),
       __01 => '42000',
       __02 => 'The estimated execution time -742267904 (sec) exceeds the limit 
of 1200 (sec).'






SPARQL query:
SELECT * WHERE { <http://dbpedia.org/ontology/Place> 
<http://www.w3.org/2002/07/owl#unionOf> ?o0.  { OPTIONAL { ?o0 ?p1 ?o1. 
}} }




Kind regards,

Lorenz
