> I am trying to report Cassandra metrics to Graphite server using
> metrics-graphite. When there is no load on the cluster everything works fine
> and all metrics are reported properly. But if some load occurs, I receive
> following exception in system.log:
> {noformat}
> ERROR [metrics-graphite-reporter-1-thread-1] 2016-07-13 08:21:23,580

> This message is repeated every second on every Cassandra node and some
> metrics become unavailable. In order to receive the metrics again, I have to
> restart all Cassandra nodes. I tried different metrics-graphite versions from
> 3.1.0 to 3.1.2 with the same issue.
