I get the error below when I try to execute a task with celery and amqp, is there a problem with my configuration. How do I fix this?

    Value overflow when storing a result:

    error: 'i' format requires -2147483648 <= number <= 2147483647

    A bigint/long value is being written into the AMQP queue, while it recognizes it as int.
    It is not a configuration issue I believe. What is the value you try to save as a result?

    I see in the stack trace:

    return self._store_result(task_id, result, status, traceback, **kwargs)

    Can you check what is the result value? Probably this is some strange value…

    EDIT: 

    task.backend.mark_as_failure(req.id, exc, self.strtb)

    So in this case it returns exc as result:

    def mark_as_failure(self, task_id, exc, traceback=None):
        """Mark task as executed with failure. Stores the execption."""
        return self.store_result(task_id, exc, status=states.FAILURE,
                                 traceback=traceback)

    Could it be the thrown exception from the task to contain a bigint status code?
