U said RF=1...missed that..so not sure eventual consistency is creating issues..

I think the messages dropped are the asynchronous ones required to maintain
eventual consistency. Client may not be complaining as the data gets commited
to one node synchronously..but dropped when sent to other nodes asynchronously..
We resolved similar issue in our cluster by increasing memta
Internode messages which are received by a node, but do not get not to be
processed within rpc_timeout are dropped rather than processed. As the
coordinator node will no longer be waiting for a response. If the Coordinator
node does not receive Consistency Level responses before the rpc_timeout
I meant to say I’m *not* overloading my cluster.
