Question about the use of JMS connections

Question

Good Morning,
I'm a new user of JMS technology. I'm having some problems with the performance of my application. Specifically, i'm developing a 24x7 application. We are using MessageListener for all consumers.
Doing performance and continuity tests I detected memory leaks in certain JMS classes. After passing a profiler tool, I saw a large amount of ObjectMessage and Message instances. We are not closing the session, MessageListeners, MessageConsumers or Connetion instances because we want to reuse them all the time, and we can't close them because we lose the high availability service.
Reading, the JMS tutorial, I'm saw this paragraph in the "Connection" section:
+"When an application completes, you need to close any connections that you have created. Failure to close a connection can cause resources not to be released by the JMS provider. Closing a connection also closes its sessions and their message producers and message consumers.+
+queueConnection.close();+
+topicConnection.close();+
+Before your application can consume messages, you must call the connection's start method; for details, see Section 3.5, "Message Consumers." If you want to stop message delivery temporarily without closing the connection, you call the stop method."+
Should I close the connection as the last paragraph say?. If so, I don't know how to do it without lose the service, because if I call "close" method on the connection and immediatelyi start it, i will lose all my consumers and producers for a little time.
Any suggestion?
Thank you in advance,
Regards

You should close a connection when you have no further use for it as this will release resources.
You must start a connection if you want to receive messages from it.
Most applications don't use stop(). However if your application needs to temporarily pause delivery of messages (to the application) for some reason, call stop(). When your application wants delivery of messages (to the application) to restart, call start() again.
