I'm confused about the observation that I "have explicitly configured Young Gen/Old Gen/Survivor size". That makes no sense to me since what I've configured is this: java -ea -javaagent:/usr/share/cassandra/lib/jamm-0.3.0.jar -Xms25G -Xmx25G -Xss256k -XX:+AlwaysPreTouch -XX:-UseBiasedLocking -XX:StringTableSize=1000003 -XX:+UseTLAB -XX:+ResizeTLAB -XX:+PerfDisableSharedMem -XX:CompileCommandFile=/etc/cassandra/hotspot_compiler -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/mnt/cassandra/cassandra-1546919408-pid19800.hprof -XX:+ExitOnOutOfMemoryError -Dcassandra.printHeapHistogramOnOutOfMemoryError=true -Djava.net.preferIPv4Stack=true -Dcassandra.jmx.local.port=7199 -XX:+DisableExplicitGC -Djava.rmi.server.hostname=10.144.162.109 -Djava.library.path=/usr/share/cassandra/lib/sigar-bin -XX:+UseG1GC -XX:MaxGCPauseMillis=500 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:InitiatingHeapOccupancyPercent=25 -XX:ParallelGCThreads=8 -XX:+UnlockDiagnosticVMOptions -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution -XX:+PrintGCApplicationStoppedTime -XX:+PrintPromotionFailure -XX:PrintFLSStatistics=1 -Xloggc:/var/log/cassandra/gc.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=10M [classpath and Cassandra configs elided]
