I was just going to tell you, This looks like it could be an issue making quorum. In order for new DBs to be written to the cluster you need to have a quorum. If you have a node that's not responding correctly it can cause issues with the data handlers waiting for a response.
Also if you are doing cluster replication over the WAN, that could be an issue as well if the nodes are to far apart and have high RTT. If that the case you may want to think about configuring your node into zones, which is a short term solution. Really doing cluster replication over WAN/Internet is not a "great" idea.
