giuseppe bottura commented on RF-7248:
--------------------------------------
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.
