Scary log messages with clustering

Hi all,

I have a cluster with two alfresco (3.2r2) running in a standard configuration (as described in the wiki pages).
Both servers share the database and the file system and the cache is configured as suggested in ehcache-custom.xml.sample.cluster

When both servers are running the log file (on both servers) starts to get full of terrifying messages:

Each key is printed more than one time, and the system seems blocked in an infinite loop (I waited for more than 15 minutes).
Worse than that, in the meantime, no alfresco is able to serve requests.
Luckily when I restart only one server, it works and no documents have been deleted.

Do you have any suggestions?

Thanks
Marco
