Last time I helped with clustering (on another J2EE server), the term thrown around was "cluster topology", which is not only the membership of the server but the organization of the nodes in the cluster. Over time servers join and leave the cluster and nodes can be repurposed. After each mutation of the topology, the version number would increment (or the hash changes).
What would help to mitigate this issue would be to have some value that indicates a state change of the server and include this in the hash calculation.
