-------------------------------

             Summary: When cluster shut down completely and restarted, some 
operations may be lost on client
                 Key: GEODE-9640
                 URL: https://issues.apache.org/jira/browse/GEODE-9640
             Project: Geode
          Issue Type: Bug
          Components: client/server
            Reporter: Eric Shu


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.
