I first noticed the issue when some operations that should have done were left undone Than I inspected the taskqueue execution with a custom routine that tracks / counts ingoing and executing tasks, a routine that I perfected long ago, and noticed the missing executions The issue isn't persistent, after a re-deployment and re-test, the same routine managed to traverse all the entities as it's supposed to TL;DR - some taskqueue tasks silently fail to execute, this should never happen, but it happens very frequently without any reason, causes damage and confusion -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
