I get this error sometimes.
Request was aborted after waiting too long to attempt to service your request. Most likely, this indicates that you have reached your simultaneous dynamic request limit. This is almost always due to excessively high latency in your app. Please see http://code.google.com/appengine/docs/quotas.html for more details.
The request that causes it has 10 seconds of latency and 0ms of cpu time. It is a simple jsp page that doesn't do anything that takes long at all. Also, my app is very low traffic, and all the times it has happened, it is the only request being processed.
What causes this?
