Question

我在星期天早上部署了一个Python用户。订户每天重新启动。从今天开始（3天后），它在启动后10-20分钟会出现ALREADY_EXISTS错误。

我现在已经重启了好几次了。每次运行正常时，都会正确检索以前的消息和进程。然后大约10-20分钟后它再次死亡。在它死亡时，它没有收到任何消息，也没有发生任何重大事件。

订阅者代码

project_id = '***'
subscription = 'pop'
subscription_id = 'projects/{}/subscriptions/{}'.format(project_id, subscription)

def subscribe(callback):
    subscriber = pubsub.SubscriberClient()
    subscription = subscriber.subscribe(subscription_id)
    future = subscription.open(callback)
    future.result()

错误

File "/usr/local/lib/python3.6/site-packages/google/api_core/grpc_helpers.py", line 54, in error_remapped_callable

我在Google Pub/Sub Reference中发现错误409表示ALREADY_EXISTS：

主题或订阅已存在。这是创建操作的错误。

这实际上没有用，因为我没有创建订阅。我只订阅已经创建的一个，如Google Cloud Docs中所述。

最后，我发现这个Github Issue遇到了同样的错误，但情况完全不同。它似乎与我的问题无关。

请帮忙。

Google Pub / Sub Python Subscriber在10分钟后获得ALREADY_EXISTS
