> --------------------------------------------------

> URL: https://issues.apache.org/jira/browse/JENA-125
> Project: Jena
> Issue Type: Bug
> Components: TDB

> Using 32-bit JVM or manually setting FileMode.direct with 64-bit JVM.
> Jena 2.6.4, TDB 0.8.10.

> There's an OutOfMemory exception when adding data to the TDB model with the
> following code:
> public class JenaAddPerfTest {
> private Model model;
> private Resource cls;
>
> @Before
> public void init() {
> File file = new
> File(System.getProperty("java.io.tmpdir")+"/test-"+UUID.randomUUID().toString());
> file.mkdirs();
>
> model = TDBFactory.createModel(file.getAbsolutePath());
> cls = model.createResource("http://example.com/class";);
> cls.addProperty(RDF.type, OWL.Class);
> cls.addProperty(RDFS.subClassOf, OWL.Thing);
> }
>
> @After
> public void close() {
> model.close();
> }
>
> @Test
> public void test() {
> for (int i=0; i<10000000; i++) {
> model.createResource("http://example.com/res"+i, cls);
> if (i%10000 == 0) {
> System.out.println(i);
> }
> }
> }
> }
> The exception happens after ~670000 iterations with -Xmx128m.
