Maybe somebody here can me point into the direction with a problem I ran into testing the graphql-kotlin library. It's using the Java Publisher interface in the library to support subscriptions via a websocket. However once about 120 subscriptions have been started and stopped that websocket becomes unresponsive. The subscriptions are stopped by calling .cancel() but they are only really stopped once the connection with the client is broken.
