I am having an issue where the connection.close() hangs. This happens intermittently. I have 3 connections established to a server:

Producer to a topic T1, Consumer to Topic T2, Consumer to TOpic T3. I establish 3 connections, 3 sessions and under each session the above topic subs/publisher

When the application is shutdown I close connections to all 3 in sequence, the first connection always closes but intermittently I see that close to either the connection to T2 or T3 just hangs. The connection in the server is active and the server after the TTL will clear off the connections.

Is there a known issue where the connection close can hang ?

Thanks
