Local task execution is using the local UrlFetchService implementation with its default timeout: 5 seconds. So, if the url that your task hits takes more than 5 seconds to respond you'll see this exception. However, this exception is from the client of the task url, not the task execution itself. The client will timeout after 5 seconds but the task should still execute to completion - we don't interrupt it. Please let me know if that's not the case.
Now, 5 seconds is clearly not enough time since the request limit for apps is 30 seconds. This is a bug, and it's already fixed. It should go out with the next SDK. In the meantime just try to ignore the timeouts. As for retries, this is a known limitation: http://code.google.com/appengine/docs/java/taskqueue/overview.html#Task_Queues_and_the_Development_Server We'll get this brought in line with production shortly. Thanks, and sorry for the trouble. Max On Sun, Dec 6, 2009 at 9:57 PM, Tristan <sp00s...@gmail.com> wrote: > I've seen this as well.
