That's 120s at the server?
What happens if that goes off? The response is closed? (a Q for james)

a stack trace could be very helpful.
There is no stack trace captured

Rob's right - RDFParser does not close a resource that is passed into the
parser. If given a resource, the caller is responsible - try-with-resources or
similar is expected.

I was reading the javadocs and these state the InputStream will be closed when
the parser is called

It is not reopening connections for one request.
If parsing starts, it has the connection until the end.

is it possible that the client had no readable connection given the
3072/55397664 entry in the http proxy log?
it should indicate that some sort of connection existed long enough for nginx
to send over 55 million bytes.

That's a really good suggestion. In the normal code flow do you ever call
stream.close() ? And is createHttpClient() re-using an existing HttpClient
object ? And is the hang only happening after some requests have succeeded ?
It is possible what is happening is that you aren't closing the
HTTPClient is not running out of connections? It is known to hang in such cases.

Hello,
We’re facing an issue with Jena reading n-triples stream over HTTP. In fact,
our application hangs entirely while executing this piece of code:
Model sub = ModelFactory.createDefaultModel();
TypedInputStream stream = HttpOp.execHttpGet(requestURL,
WebContent.contentTypeNTriples,
