- If a machine swaps out amd it needs more RAM anyway. One of our machines, a
- sun 4/330 showed this symptom. It went away after upgrading from 8MB to 32MB.
- One should take a close look at the output of vmstat -s. Look at the rows
- titled "swap ins" and "swap outs". If the "swap outs" value is higher than
- "swap ins" / 10000, I suggest adding memory.

- Btw, are you running tmpfs ?
