I believe your original problem was that you aren't writing any output when this service call is happening (and it takes quite a bit of time -- half a minute or more), which causes your web server or client to give up its wait for data.

One fix to this is to output something while processing -- small HTML comments, once per second, are a good option. How are you calling the service?

Alternatively, you could try to fix the root cause (why is the service call slow?)
