RDFDataMgr write does not work with milion objects

问题

I have java application which works with jena tdb. I have 3 milion objects in the db and when i want to make export on jena i am having problems.

For export i tried with:

RDFDataMgr.write(file, model, Lang.RDFXML);

and also with:

RDFWriter writer = model.getWriter("RDF/XML");
writer.setProperty("allowBadURIs", true);
writer.setProperty("relativeURIs", "");
writer.setProperty("tab", "2");
writer.setProperty("showXmlDeclaration", "true");
writer.write(model, file, null);

But non of this worked. So my question is how can i fix this problem?
