I find nothing in the log concerning this issue.

I try to do your suggestion.

Not quite. When you add replica 3, it will be synchronized to the leader.
So I'd shut down the solr node with the bad replica, add the new replica and then delete the
old one.

The disturbing bit is that the replicas for out of sync in the first place.
Anything in the logs that gives any clues as to why?
