Working on the same Application Nikolai mentioned before, App Engine more-than-sporadically returns Server Error 500. Our application is written in Python, using Memcache, URL Fetch, TaskQueue APIs, the Datastore and a zip-imported version of Django 1.2.3 (some people cared about Django versions here).
Trying to find out what part of the code/which API calls caused the latency and the DeadlineExceededErrors we installed Guido van Rossum's Appstats as the first django middleware, and even the code of our Benevolent Dictator for Life is not available all the time (a good indicator that it must be a system defect as his code is perfect anytime ;)) Unfortunately, Appstats can't log 500er errors, but if some Googlers consider it useful to have Appstats results, it's living here: http://190-fabian.latest.dctptv.appspot.com/appstats Looking forward to hearing from you and seeing some changes on the system status page, Fabian On Sep 23, 2:50 pm, Nikolai <[email protected]> wrote: > We're also having lots and lots of deadline exceeded errors in our App > since about 12 hours.
