> Cluster setup: Ubuntu 18.04-LTS, cassandra-3.11.10. One DC, 3 nodes, 2 replication factor;
> Using an injector to filter and drop MUTATION message between one node and the other two (drop MUTATION messages sent from node 1 to node 2, 3 and drop MUTATION messages sent from node 2, 3 to node 1). At the same time, inserted same key, different values on node 1 and node 2. When insertion happened, MUTATION message drops were caught on both node 1 and node2. Then we observed the different values for that key on two nodes and observed all three nodes disconnected from each other.
