title: What causes "Request was aborted after waiting too long to attempt to service your request"?
body: <p>What causes "Request was aborted after waiting too long to attempt to service your request"?</p>
  
  <p>It seems the result of some sort of internal timeout, but I don't know where this is configured.
  We're currently using autoscaling, and that error was the result of a temporary increase in the number of tasks in our taskqueue. Shouldn't autoscaling have created more instances to handle that request?</p>
  
  <p>Also, if a task in Cloud Tasks fails with "Request was aborted after waiting too long to attempt to service your request", is that task retried, or is it removed from the queue?</p>
  
  <p>Edit: I found the problem.
  This was the configuration for scailing in our app.yaml:</p>
  
  <pre><code>basic_scaling:
    max_instances: 2
  </code></pre>
