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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
