> In Geode, client keeps track of events received based on EventID. If duplicate events received from server, they are thrown away.
> The current EventID takes parts of membership ID information, and it seems not adequate enough if whole cluster is down. (The coordinator is down and member viewId will start from 0 again.) This can lead to same event ids are generated, and cause client miss CQ events, etc.
