I'm using the latest maintence version of SoapUI (not pro). if I submit a small SOAP message, it works. When I submit a large message I get a timeout. I tried changing the preferences, HTTP settings, socket timeout to a really large number (x10) but it doesn't seem to actually increase the time it takes to actually get the timeout message. I tried setting it to 0 and get the same result.
