I tried to reproduce this (by first adding your rule, then deleting it,
adding it again, rebooting), but got no crash. 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.
