Dear all, My Cassandra 082 server had very large swap memory. JConsole show memory used just 2.9GB. But htop (top) show Cassandra process take 8700MB.
Here is my config: MAX_HEAP_SIZE="6G" HEAP_NEWSIZE="400M" JVM_OPTS="$JVM_OPTS -XX:+UseParNewGC" JVM_OPTS="$JVM_OPTS -XX:+UseConcMarkSweepGC" JVM_OPTS="$JVM_OPTS -XX:+CMSParallelRemarkEnabled" JVM_OPTS="$JVM_OPTS -XX:SurvivorRatio=8" JVM_OPTS="$JVM_OPTS -XX:MaxTenuringThreshold=2" JVM_OPTS="$JVM_OPTS -XX:CMSInitiatingOccupancyFraction=75" JVM_OPTS="$JVM_OPTS -XX:+UseCMSInitiatingOccupancyOnly" JConsole also show Memory Pool "Par Survivor Space" always full (41MB/50MB) and never reduce. Could you help me? Thank a lot for support.
