Vince P.S. While step-debugging a task, I noticed that they seem to time-out very quickly--within about 5 seconds. Is this intentional? Here's a partial stacktrace: Dec 4, 2009 3:03:58 PM com.google.appengine.api.labs.taskqueue.dev.DevQueue runTask SEVERE: Exception executing task 24b5a6e4-c327-4bc6-bc4f-51f838f3d1a5 on queue write-behind-task com.google.apphosting.api.ApiProxy$ApplicationException: ApplicationError: 5: http method GET against URL http://127.0.0.1:8080/_ah/queue/write-behind-task?watchdog=839445f1-2c77-4c2c-bf32-81b88d5e092etimed out. at com.google.appengine.api.urlfetch.dev.LocalURLFetchService.fetch(LocalURLFetchService.java:214) at com.google.appengine.api.labs.taskqueue.dev.UrlFetchJob.execute(UrlFetchJob.java:53) at com.google.appengine.api.labs.taskqueue.dev.UrlFetchJob.execute(UrlFetchJob.java:46) at com.google.appengine.api.labs.taskqueue.dev.DevQueue.runTask(DevQueue.java:221) at com.google.appengine.api.labs.taskqueue.dev.LocalTaskQueue.runTask(LocalTaskQueue.java:313) On Thu, Dec 3, 2009 at 7:01 PM, Max Ross (Google) <[email protected]<maxr%[email protected]> > wrote: > Vince, > > We added a last minute fix for this in the SDK that just went out.
