Getting SocketTimeoutException while testing my request

Hi

I downloaded soap-ui pro 2.5.1 and tried to test my requests for my webservice.
It works fine for small files. But when i try to test large files say 2MB, i am not able to get the response.
Instead i see the following error in the soap ui logs.
After debugging in eclipse i saw that the my service class is executing the request properly and the "OK" response is also getting generated,
but somehow it is not able to reach the soap-ui.

Can someone explain to me how to resolve this?
