Yun Tang commented on FLINK-12096:
----------------------------------

[~yogesh_n] Would you please provide more information such as exception stack, jobamanger and taskmanager logs. We actually cannot get any helpful messages from your plain description. If no exception appeared, you could login the machine which contains the stuck task to see where java process hangs and shares the screenshot to us. It would also be welcome if you could reproduce this with specific codes and share it to us.

Moreover, in my point of view, {{RockDBStatateBackend}} actually behaves almost the same as {{FsStateBackend}} except the performance for users. And I cannot understand what "FS State backend was used because the counter value state was not getting updated from the first record itself when using RocksDBS State Backend" means here.

To be honest, from my experience, the problem you describe here might not be caused by a Flink block bug. If you don't mind, we should better discuss in the user mail list first and then create a issue here if we confirm this is really a bug.

> Working on a job to dynamically create counters for a keyed stream using counter value state and FileSystem State Backend. It was observed that the counters are stuck after a few records which is most probably because of the counter value state not getting updated. 
> FS State backend was used because the counter value state was not getting updated from the first record itself when using RocksDBS State Backend.
