   Looks like there is an intermittent failure in 
`TestScmHaFinalization#testSnapshotFinalization`. However, it is the leader, 
not the SCM that finalized from a snapshot, that hit the error:

   The error is
   ```

   ```
   
   Which indicates the leader scmNode-1 did not cross the 
`FINALIZATION_COMPLETE` checkpoint in this check, even though the logs show 
that it already had earlier. I will need investigate this.
