What's very curious is the fact that logs on both cluster nodes indicate that the elements are added to the cache.

Process as an add. | The problem is that on node 2, the number of cache contents does not go up like it does on node 1. Cache contents on node 2 remain the same after the operation. If I execute the same operation on node 2, then the execution goes as slow as on node 1 before it had populated its cache. Node 2's cache contents go up then, and reach the same level as on node 1. So it looks like the caches of both nodes operate independently, regardless of what the logs say. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4256404#...
