Jonathan Ellis updated CASSANDRA-6541: -------------------------------------- Since Version: (was: 0.3) > New versions of Hotspot create new Class objects on every JMX connection > causing the heap to fill up with them if CMSClassUnloadingEnabled isn't set. > ----------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-6541 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6541 > Project: Cassandra > Issue Type: Bug > Components: Config > Reporter: jonathan lacefield > Assignee: Brandon Williams > Priority: Minor > Fix For: 1.2.16, 2.0.6, 2.1 beta2 > > > Newer versions of Oracle's Hotspot JVM , post 6u43 (maybe earlier) and 7u25 > (maybe earlier), 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. Adding: > {noformat} > JVM_OPTS="$JVM_OPTS -XX:+CMSClassUnloadingEnabled" > {noformat} > The the options in cassandra-env.sh alleviates the problem. -- This message was sent by Atlassian JIRA (v6.2#6252)
