[google-appengine] Re: Error occurs after 30-40 consecutive urlfetch

Hey Chris, >From reading the thread history, it seems that there are potentially two issues brought up by kyeongwook Ma and Dustin Oprea. Although both see an expired context, one is about UrlFetch calls and the other is about Datastore API calls. The mechanism underlying potentially both of th

I get this error quite often as well. I am using standard environment, and as was mentioned, the request itself is not a long one, but under a second. On Tuesday, August 9, 2016 at 8:29:30 AM UTC-6, kyeongwook Ma wrote: > > Hi GAE support, > > I am a developer using the GAE with Golang and gin. >

Apologies for the follow-up, here's an example of a trace detail showing exact latencies for various RPC calls. This can be very useful. On Tuesday, August 9, 2016 at 10:29:30 AM UTC-4, kyeongwook Ma wrote: > > Hi GAE support,

[google-appengine] Re: Error occurs after 30-40 consecutive urlfetch

Thanks for sharing your issue here. Based on the expired context error you are receiving, I suspect Evan is most likely correct here. Nevertheless, more information would definitely help with narrowing down the range of possible issues here: - You mention sending 30 to 40 consecutive urlfet
