Chaitanya Yalamanchili - Quick question.  I'm saw a new issue which I believe is associated with the same bug.  I had my consumer group hang again (all partitions this time).  But in this case, the stream/assign/list monitoring endpoint actually says nothing is using the consumer group; it just returns an empty array.

 

This is still true even after duplicating the consumer group to another name and using the duplicated one in the app (which is using the new consumer group and running properly).

 

So, it appears that the cursor/assign/list endpoint is just not working at this point for this stream.  Have you seen that symptom and do you believe its related to this issue normally?
