I'm looking at my tomcat using jconsole and I'm trying to understand why the heap size varies between 0.4GB and 1GB.
I thought I told it to start at ~1GB and use no more than ~6GB.
Can anyone explain what is going on.
My commandline has these memory and GC options:
java -XX:NewSize=700m -XX:MaxNewSize=700m -Xms1202m -Xmx6014m -XX:MaxPermSize=256m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:SurvivorRatio=20 -XX:ParallelGCThreads=4
