On Linux FC 6. The machine physical memory is 4G.

After machine reboot, start JBoss and deploy application, the total memory usage is about 700M. After running JBoss for several hours, the memory used is increased to 3.5G.

$ ps -eo rss

Adding all used memory up, the total is about 580M. where does the rest memory go?

$ top
