I've recently started seeing these issues, there is a very simple routine that triggers 8-9 async get's and then calls .get_result's on them
It seems a deadlock occurs on one of the(?) items and for some reason the .get_result fails on that item, for that instance, persistently, for 1+ minutes I'm guessing this could be related to an issue of ndb's instance caches This happens to my app's users on signup, very frequently, I'm losing users since all they see are errors on signup (The routine is an on-signup routine, so when it fails, it's triggered again on every visit/request, which probably causes the issue) Spamming an instance with the same .get_async / .get_result routines might trigger/reproduce the issue -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
