   Hi @Swarvenstein, I notice the engine log contains the following message
   ```
   SparkTBinaryFrontendService: Received request of closing SessionHandle [0d8be737-c71d-4870-954b-831835390f09]
   ...
   SparkSQLSessionManager: SessionHandle [0d8be737-c71d-4870-954b-831835390f09] is closed, current opening sessions 0
   ...
   SparkSQLSessionManager: Session stopped due to shared level is Connection.
   ```
   It indicates that you are using the CONNECTION engine share level, which means every connection(session) will create a new spark application, and once the connection(session) is closed, the engine will self-terminate immediately to save resources.
   
   If you want to share the engine(spark application) across sessions(connections), please set `kyuubi.engine.share.level` to another options like 'USER'
