Subject Cassandra 082 - Large swap memory
Date Fri, 26 Aug 2011 03:36:56 GMT
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.
