I have a page with several drop downs using a4j:support to call a listener and then rerender portions of the page. When I navigate to the page and select the drop downs the ajax calls will call my ActionListener and the updates and refreshes work correctly. However after just a few calls the ActionListener stops getting called. The log shows that A4j is making the ajax call and reports the return value as success but the listener never gets called. At that point ALL ajax calls stop working and just seem to be sending the calls out and never reaching their destination and never reporting the error.

Does anyone have experience with richfaces under load with complex ajax interactions? The demo is nice but it is not very complex. All the ajax is from richfaces with no homegrown ajax. I have tried isolating this using regions, output panels etc but no difference.

I have to send this to production soon and I would hate to rewrite this for another framework.

I am using 3.1.2 SP1 with MyFaces 1.1.5 and Facelets 1.1.12
How can I debug this?

Thanks
