---------------------------------------
I've seen at least 3 users in the field hit this issue, in each case enabling
CMSClassUnloadingEnabled solved the issue.
> Add JVM_OPTS="$JVM_OPTS -XX:+CMSClassUnloadingEnabled" to cassandra-env.sh

> Project: Cassandra
> Issue Type: Bug
> Components: Config
> Reporter: jonathan lacefield
> Priority: Minor
>
> Newer versions of Oracle's Hotspot JVM , post 6u45, are experiencing issues
> with GC and JMX where heap slowly fills up overtime until OOM or a full GC
> event occurs, specifically when CMS is leveraged. Running repair exacerbates
> this issue. The configuration added to the Summary line helps alleviate this
> behavior and should be included in the C* config files by default.
