Summary: Add JVM_OPTS="$JVM_OPTS -XX:+CMSClassUnloadingEnabled" to
cassandra-env.sh
Key: CASSANDRA-6541
URL: https://issues.apache.org/jira/browse/CASSANDRA-6541
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.
