MeToo - I get this too -
com.google.appengine.api.labs.taskqueue.TransientFailureException:
Unknown
at
com.google.appengine.api.labs.taskqueue.QueueApiHelper.translateError(QueueApiHelper.java:
60)
at
What's worse is that this occurs on a recurrent task that schedules
itself - After failures like this, I end up with 2, 3, sometimes 5
tasks all doing the same thing - the task queue management system
keeps scheduling the failed task..
Luckily, the app is structured so that repeated concurrent runs does
no harm apart from using up CPU. What can I do - apart from monitoring
the queue on a daily basis and purging the extraneous tasks ?
