Subscription processes hangs forever

[bisws007]

Hi,
Publish process publishes only 2 messages. Ran subscription process on my local and messaged processed successfully. 2nd time I ran the subscription process once again on my local and there is no messages but the subscription process hangs forever. Can you please explain why?
I am using google pub-sub version 0.21.1-beta.

I think I've been seeing this issue in production as well. Same version as above. However it's only in one of our services. How can I help debug this issue? I've seen similar behaviour? And it happens 1-5 times per day.

Need to verify if this is a reliability bug or not.

@bisws007 Could you share the code you're using to subscribe? Generally the subscriber won't stop until you call subscriber.stopAsync().

In v0.21, there was a bug that could cause messages to be stuck in the subscriber that prevents termination. That bug has been fixed now. Do you think you can try again with v0.26?

I'll close this for now due to age. Please reopen if required.
