[Resolved] Load Test - with datasource - is this correct ?

I'm new to Pro (though have used normal for years). I'm trying to set up a load test of our servers using data driven testing. So I define a datasource initially, then run through the most commonly called services (effectively emulating a user), and then Loop at the bottom back to startup (not up to datasource)



Is this the correct way of doing this for a load test ? When I do get failures - it'll eventually say "Load Test ended" - but I can see requests coming in to the server for several minutes after this and have additional errors in the SoapUI log after this has finished.

Unrelated - I'm also getting an "org.apache.http.conn.HttpHostConnectException - Connection refused." occasionally from the tests (randomly - there's nothing wrong with the request and re-running it is fine). There's nothing in the server logs so I think my question is - is this message is coming from SoapUI (I realise the resolution is external - probably I need to up number of free threads that apache has to work with in this case or there's some issue with my internet connection).
