Hi Abdul, When I have seen dropped messages, I normally double check to ensure the node not CPU bound.
If you have a high CPU idle value, then it is likely that tuning the thread counts will help. I normally start with concurrent_reads and concurrent_writes, so in your case as reads are being dropped then increase concurrent_reads, I normally change it to 96 to start with, but it will depend on size of your nodes. Otherwise it might be badly designed queries, have you investigated which queries are producing the client timeouts?
