zLinux 5.4, SUSE 10.2. Running one instance of WebSphere 7 with 6 profiles / JVM instances. I started with 3 GIG, went to 5GIG, now at 6 GIG, and free memory still drops little by little, SWAP eventually begins to grow and finally performance goes to heck. Just like Windows (ouch) you reboot and everything is cool for a few more days....
I have read and heard the lectures on zLinux taking all you give it, but I need it to STOP.
