Task Queue - Transient Errors

[Santiago]

Hi everyone, In the last days I've been seeing on my application a lot of Transient Errors when I try to use task queues. is this happening to anyone else? do you know what actually happen when this error is raised? all i get from GAE documentation is "There was a transient error while accessing the queue. Please try again later"  but I'm not very confortable about having my logs flooded with this! thanks!

Hello,

Yes, we have been getting these too....today was particularly bad because of the issues with the task queues - https://code.google.com/status/appengine/detail/taskqueue/2013/04/18#ae-trust-detail-taskqueue-add-latency

We believe the attempt to grab the task from queue is failing temporarily, and it wants you to try again in a another second or so.

Hello Santiago,

Transient errors happen sometimes, there's not a whole lot you can do to prevent or reduce them. 

One mitigating strategy is to attempt to add a task; if you get an error, sleep for 500ms - 1sec and try again. Here's some more discussion on the topic: http://grokbase.com/t/gg/google-appengine/12ck1skbqy/transient-error-when-attempting-to-add-task-to-queue-fails-on-retry

Thanks Vinny, It's not happening anymore but to mitigate that next time it happens I will try with your strategy,
