On one of our applications (steprep), we see periods of extreme burstiness in errors.
For example, from 8.32a to 8.35a (Sept 10, log time), we saw: - 20 transaction could not be committed errors - 14 datastore timeouts, or unavailable - 47 deadline exceeded errors This code, which is largely background tasks and not really impacted by end-user access, runs well at other times during the day. We also have a demo server with similar code and data characteristics (steprep- demo) that does not see these issues, though it does do only about a third to a half of the background work that our primary does. I fully understand that a system like App Engine has transient issues and that it's important for us as developers to architect our software around this. I fully understand that resources like UrlFetch rely on non-Google services and may be the root of (seemingly random) DeadlineExceededErrors. However, I've seen this behaviour before, and I believe it was attributed to localized load (i.e., the particular set of applications that were on the same physical hardware). Is it possible that this is happening again? We've only seen this level of errors for perhaps the last 7-10 days. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
