Brandon Wulf commented on CASSANDRA-9625:
-----------------------------------------
I too upgraded to 2.1.13 hoping to fix this issue.
I upgraded from 2.1.8 primarily because the graphite metrics reporter kept
dropping and for a few weeks I saw no more issues. Then, after we added some
new nodes with SSDs, this seems to be effecting the fast nodes. Maybe the old
nodes were having enough io wait time injected to negate a race condition
causing this issue?
> GraphiteReporter not reporting
> ------------------------------
>
> Key: CASSANDRA-9625
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9625
> Project: Cassandra
> Issue Type: Bug
> Environment: Debian Jessie, 7u79-2.5.5-1~deb8u1, Cassandra 2.1.3
> Reporter: Eric Evans
> Assignee: T Jake Luciani
> Attachments: metrics.yaml, thread-dump.log

> When upgrading from 2.1.3 to 2.1.6, the Graphite metrics reporter stops
> working. The usual startup is logged, and one batch of samples is sent, but
> the reporting interval comes and goes, and no other samples are ever sent.
> The logs are free from errors.
> Frustratingly, metrics reporting works in our smaller (staging) environment
> on 2.1.6; We are able to reproduce this on all 6 of production nodes, but not
> on a 3 node (otherwise identical) staging cluster (maybe it takes a certain
> level of concurrency?).
> Attached is a thread dump, and our metrics.yaml.
