Got it. I think one workaround is to modify the brokerDeleteInactiveTopicsMode config of the broker with delete_when_subscriptions_caught_up and acknowledge messages.

BTW, I just tested close after unsubscribe with the Java client, it’s okay to do that. I’ll look into the issue with the C++ client soon.
