Description

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]

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?
