The problem occurs on a machine with 512MB RAM and 1024MB swap. top reports
about 200MB free RAM (not actually free, but used for cache and buffers). Used
swap space varies between 15MB and 25MB.
iostat (and sar) report that the swap partition is busy (about 15 transaction
In my opinion the system shouldn't swap at all while there is enough RAM
available. Even if one considers that swapping out unused program parts to use
the freed RAM for harddisk cache might be more efficient there's absolutely no
justification for this heavy swap activity.
I've disabled swap (via swapoff) to avoid burning out yet another harddisk (one
rests in peace already due to a similar problem). This resulted in about 20MB
less free RAM, but the system appears to run fine. I'd prefer a less drastic
Are there any options in /proc/sys I could use to make swapping out less

Steps to Reproduce:
2. Wait a few minutes.
3. Watch HD activity light flicker.
Actual Results: Heavy swapping.
Expected Results: No swapping.
The software running on this system is making heavy use of anonymous mmap().
