    Description

      Currently plasma rpVersion is 16bit. If it overflows and recovery log/data log continue to have the overflow versions along with the previous versions in valid Offset range, it will lead to choosing a stale RP version. This can result in RollbackToZero where GSI cannot find a common RP version. This is a corner case. Please see details on steps to repro on CBSe 13198.
