I think I know the problem for the pending messages. I will confirm in 2 days since I need to more time to test before I can exactly tell that this was the problem. Somebody else should test this, and try to reproduce it.
Here is the scenario. I have 2 types of jms clients. One client resides in code deployed in war file on jetty server. It collects some data from some other data source every 'x' secs. If there is a threshold exceeded on some value of a field, it sends a JMS message to the queue to raise an alarm. So, since the code is deployed in a war file, ActiveMQConnectionFactory was created once and used later to create connection, session etc. There is another client of JMS which was called from a script. The script called a simple java client which created a JMS message and sent it to a jms queue. Since this does not reside on any webserver/appserver, the QueueConnectionFactory was created every time the script was invoked. This in my opinion caused the problem since it was repeatedly creating the ActiveMQConnectionFactory, a huge object. Solution: I moved the jms sender code to war file deployed on jetty server. I implemented a web service which would send the jms message to the queue. The script which calls the java program now became a web service client which send the jms message. So, since the code sits on jetty, the ActiveMQConnectionFactory is initialized once and used over and over again to create sessions etc. I have tested it for over a couple of hours, and have sent more than 100 messages from the 2 clients together, and I have not seen a pending message yet. I am hoping that this was the problem! Thanks for all your help.
