What does Read and _Trace dropped mutations mean? There is no tracing
enabled on any node in the cluster, what are these _TRACE dropped messages?

INFO  [ScheduledTasks:1] 2019-07-25 21:17:13,878
MessagingService.java:1281 - READ messages were dropped in last 5000 ms: 1
internal and 0 cross node. Mean internal dropped latency: 5960 ms and Mean
cross-node dropped latency: 0 ms
