Jonathan Ellis commented on CASSANDRA-6541: ------------------------------------------- [~nickmbailey] did you ever file an openjdk bug, or are we convinced this is the new Working As Designed? > 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)
