Hey Andy,
My entire program is run on one jvm as follows.
public static void main(String[] args) throws IOException{
DatasetGraphTDB datasetGraph = TDBFactory.createDatasetGraph(tdbDir);
/* I saw the BulkLoader had two ways of loading data based on whether
the dataset existed already. I did two runs one with the following two
lines commented out to test both ways the BulkLoader runs. Hopefully
this had the desired effect. */
datasetGraph.getDefaultGraph().add(new
Triple(Node.createURI("urn:hello"), RDF.type.asNode(),
Node.createURI("urn:house")));
datasetGraph.sync();
InputStream inputStream = new FileInputStream(dbpediaData);
BulkLoader bulkLoader = new BulkLoader();
bulkLoader.loadDataset(datasetGraph, inputStream, true);
}
The data can be found here
http://downloads.dbpedia.org/3.6/en/mappingbased_properties_en.nt.bz2
I appended the ontology to end of file it can be found here
http://downloads.dbpedia.org/3.6/dbpedia_3.6.owl.bz2
The tdbDir is an empty directory.
On my system the error starts occurring after about 2-3minutes and
8-12 million triples loaded.
Thanks for looking over this and please let me know if I can be of
further assistance.
