      Deploy and start a broker.
      Build the attached reproducer and execute the MqttTest.java file
      Allow to run for several minutes
      Kill the client with kill -15 (SIGTERM) or kill -9 (SIGKILL)

      Take a heap dump of the broker and query for leaking objects. E.g:

      select * from org.apache.activemq.artemis.core.paging.impl.PagingStoreImpl psi

    • Critical

      In a scenario with a MQTT publisher producing to many topics with an OpenWire wildcard consumer consuming from a single matching topic, BindingsImpl, PagingStoreImpl and associated objects are never cleaned up, even when the clients exit, resulting in a large buildup of objects in the PagingManagerImpl.
