---------------------------------
Summary: Histogram overflows potentially leading to writes failing
Key: CASSANDRA-14867
URL: https://issues.apache.org/jira/browse/CASSANDRA-14867
Project: Cassandra
Issue Type: Bug
Components: Streaming and Messaging
Environment: cassandra 3.11.1 on ubuntu 16.04

I observed the following in cassandra logs on 1 host of a 6-node cluster:
ERROR [ScheduledTasks:1] 2018-11-01 17:26:41,277 CassandraDaemon.java:228 -
Exception in thread Thread[ScheduledTasks:1,5,main]
java.lang.IllegalStateException: Unable to compute when histogram overflowed

At the same time, this node was failing all writes issued to it. Restarting
cassandra on the node brought the cluster into a good state and we stopped
seeing the histogram overflow errors.
Has this issue been observed before? Could the histogram overflows cause writes
to fail?
