CLUSTERIP keeps global state, so it might be that some previous actions using it contributed to the crash, although its strange that it crashed in ip_tables, not in CLUSTERIP itself. Did you added/deleted/flushed/... any CLUSTERIP rules before the crashes? If you can find a way to reproducibly cause the crash it would help a lot.
