I had one of my apps start timing out during the compile/build process
(that's good and bad!!! - good = hey, I am writing a LOT of code now!!!!).
You can try this setting;
I think the default was 30 or 60 seconds. But I bumped it up to 180. (select that option - a dialog box will pop up - you can then enter a longer time for the build process)
So, give the above a try - it is a setting, and you can as your code base grows find that the default time is insufficient for the build time/process.
the above setting fixed my experience in this regards,
Edit: hum - I missed quite much you are using the hosted builder - so, I not 100% sure above applies to your case.
