    Java is taking more memory than configured!

      Hi All,


      I have observed suspicious memory behavior in Jboss/Jvisulavm.


      I have JBoss7.1.0 running on Windows OS. Have configured configurations as below

      "-Xms64M -Xmx512M -XX:MaxPermSize=256M"

      However, when i monitor in JvisualVm,

      "Size: 454,426,624 B Max: 536,870,912 B Used: 299,350,616 B"

      As mentioned above, Max size is more than configured value and same goes for perm size as below:

      "Size: 208,928,768 B  Max: 268,435,456 B Used: 151,287,656 B" as we have maxpermsize=256MB.


      is this normal behavior or any memory leak issue?and Please advice.
