      Description

      It is possible that the last loggged zxid as reported by all the servers during leader election is not the last zxid that the server can upload data to. It is very much possible that some transaction or snapshot gets corrupted and the servers actually do not have valid data till last logged zxid. We need to make sure that what the servers report as there last logged zxid, they are able to load data till that zxid.
