Re: out-of-memory error

You don't indicate if you are closing the MessageProducer or Session
instances.

If not, you have a memory leak.

You can also get out of memory errors if you are publishing
non-persistent messages

to slow consumers and haven't set a message expiration interval.

Hi OpenJms,

I am Thandesha and getting the
following error some times. What might be the problem?

public boolean
queueMessage(String message) throws Exception{

Session sess;

MessageProducer sender = null;

try {

sess = sh.getSession();

sender = sess.createProducer(sh.senderDestObj);

TextMessage txtMessage = sess.createTextMessage(message);

sender.send(txtMessage);

sh.putSession(sess);

} catch (Exception e){

throw e;

}
