--------------------------------------------------------

This specific issue doesn't appear anymore, but we can still have too many subviews, as described in the next comment.
Note that the MergeView itself is correct and lists the correct members. It is the subviews which are incorrect.

> II wasn't able to reproduce that with a simple program. But I observed that merge was preceded by an ifdown/ifup on host 192.168.56.6. That member lost all others members, but it still present in their view.
> Example:  
> {code}
> {A, B, C} => {A, B, C} and {C} => {A, B, C}
> {code}
