Can you attach your .war file? I will deploy to labs for testing.

Attached pushservice.war that works as expected on my local deployment.

It appears that this problem is transient – after restarting the server, I had good results with the browser I tested with, but then observed a storm of traffic for a connected mobile device. Please leave your server running locally over a period of time and test it periodically with a number of browsers while keeping an eye on the network activity. I will monitor the labs deployment to look for the problem again.

Restarting tomcat and clearing the work directory seems to temporarily fix the problem. So, this appears to be a transient state that either the push client or the server enters (but it is a very severe failure since it could exhaust either a mobile user's bandwidth cap or result in a high network use bill from amazon for us.)

The infinite loop issue cannot be reproduced any more, most probably it was caused by browser caching. We can open this issue again if the problem re-occurs.
