Description:

When a node receive multiple snapshot from old leader and new leader, the new snapshot can't be accept forever because the progress not match.

How do you solve it?

First verifyLeader, then check if commitId and commitTerm matches last snapshot, if not, just return error.
If the node has not received snapshot for a long time (default is 5min), will convert to follower again, so it can receive another snapshot.
