--------------------------------------

Hi, we are facing the same 100%CPU problem with an application that is in production. We are using RichFaces 3.3.3 final;
since we cannot move to RichFaces 4, and it seems that there is no plan to release 3.3.4 (https://issues.jboss.org/browse/RF/fixforversion/12314617), we think to test the fix available  on http://dl.dropbox.com/u/12264764/richfaces-impl-3.3.3.Final.jar 

Looking around on the forums, I found also the suggestion to setup org.ajax4jsf.SERIALIZE_SERVER_STATE=true, but I didnt' find any feedback about the successful appliance of this tip.

Thanks in advance for any feedback

> Concurrent requests on a4j components causes infinite loop. While one request is being proccessed by restoreChildState method, another request is senT for proccessing. It causes the code to get stuck in hashmap.get() as the hashmap is not synchronized and causes infinite loop.
