Hi,
I am using kernel 2.4.4. I have 32M RAM with a 10M Ramdisk. Now my problem is
that
the Ramdisk is cached in the RAM(4 - 8M!). Is it possible to set the size of
the
cache to a limit or to disable the cache complete?

I'm confused, top says that you have 21.4M free. If your 10M ramdisk was being cached in 4M of RAM
then surely you'd have at most (32-14)=18M free?
While we're on the topic of RAM usage, can anyone tell me how you find out how the shrd memory (see
top output above) is broken down into seperate libraries.
Thanks,
Alex

You can do this by changing values in the /proc file system.
Refer to the docs in the kernel source.
