Geez, you have s390? Can you give me a free SSH account? :) I heard virtualization on s390 is ancient but one of the best in the world :)
Well its not mine, i just manage it
Actually, from kernel point of view, you have low free RAM. Somehow you need to make the kernel dedicate lesser portion of RAM for page cache. Too bad I can't find one, but the closest I can find is /proc/sys/vm/vfs_cache_pressure. read Documentation/filesystems/proc.txt for further explanations.
But if a processes needs more ram, the kernel would take it from cache first right? Or do i have that wrong?

For fun, try something like: strings -t x /dev/<your swap device> | head -30 and see in case you see your shell history there :)
It would be nice to know what pages are in there, If its nothing but sutff that isn't going to ever go back on the run que then i wouldn't worry about it. But it would be nice to know what is in there. Eli -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
