Alex Krasov commented on RF-7248:
---------------------------------

Can you please post a link to the mentioned patch so we could take a look?
The problem is seriously hitting our production servers, so I'm considering to adopt this patch to 3.3.3. 
Unfortunately we can't upgrade to 4.0 in the foreseeable future...

Thanks.

> 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.
