Hi,
Is it normal that inactive memory are not recycled
back to unused memory in Red Hat Linux after a long
period of time (i.e. after a week)?
I'm using Red Hat Linux Enterprise
2.4.9-e.25enterprise with 4G RAM and running a Java
server application that consumes around 22% RAM
resources (I used top to monitor this). While
conducting stress tests on the server app, the RAM
memory usage grew to around 50%. After shutting down
the server app, the memory used is still around 50%.
Here's a snapshot of the /proc/meminfo:

Any constructive advice/tip will be greatly
appreciated. Thanks! :)
