    JBoss 7.1.1 strange memory usage

    Milan Milanov Newbie


      I was profiling our Spring MVC + Hibernate app when I discovered a strange behaviour - the memory kept getting higher and then suddenly dropping (ano not because of the GC). Then I tried monitoring only JBoss, without deploying our app. I've applied a screenshot to demonstrate - the memory drops from 150M to 25M and does this continuously.

      The options with which JBoss is started:

      -Xms256M -Xmx1024M -XX:MaxPermSize=512M -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC


      I tried clearing the tmp and deployment files and restarting but the behaviour is the same. Any ideas about it will be appreciated.
