I have this error constantly, though I'm not explicitly using urlfetch. I'm just using datastore and memcache. As I'm in the early stages of this project, I only recently noticed it happening more frequently after I implemented session management on top of datastore and memcache, but, now, as I actually explicitly push data into memcache, it is now happening constantly. Most often, I'll get this error every time until I flush, it will work once, and then I'll get this error every time afterward.
The requests that are inciting the issue are very simple (try *get* from memcache, do *get* from datastore, *put* to memcache), so they're very quick. The request either completes or fails within a second. Any ideas? <-- Current user reconcile here. 2016/09/01 03:00:42 DEBUG: Session save not necessary: [DCRBDGRY6RMWANCSJXVLD7GULDH4NZEB6SBAQ3KSFIGA2LP45IIQ] 2016/09/01 03:00:42 DEBUG: Got session: [DCRBDGRY6RMWANCSJXVLD7GULDH4NZEB6SBAQ3KSFIGA2LP45IIQ] 2016/09/01 03:00:42 DEBUG: Found user in session. <-- Request-specific handler logic here. 2016/09/01 03:00:42 DEBUG: Cache hit: [type.family:522450f6795592f844a27213a2dddf8de169f204] 2016/09/01 03:00:42 ERROR: context expired before API call datastore_v3/Put completed request URL: /api/1/type/family/522450f6795592f844a27213a2dddf8de169f204 panic: Call error 3: invalid security ticket (context expired) Maybe if I could understand the nature of the failure and how it might potentially be tricked to fire so early I might be more helpful in providing more information? Thanks.
