JBoss Cache, replication problem on server restart

Hi everyone,
I configured a Jboss cluster, with Jboss portal and a replicated cache. After some months I noticed an error that occurs during the restart of one of the nodes in the cluster, it seem that the node is not able to receive the cache informations, this is the error:
