RE: Dynamips Taking full utilisation of memory on Ubuntu, pls

Try this

1. Is Idle PC correct ?
2. Boot Ubuntu in text mode, no GUI. This made big difference for me. Then
connect to virtual routers from another PC via network.
3. Do you have enough memory in your PC ?
4. In text mode use command "top" to see mem usage.

On my PC I do this:
To boot in text mode:
# sudo update-rc.d -f gdm remove

To boot in graphics mode:
# sudo update-rc.d -f gdm defaults

I did run up to 9 routers without problems.
Here is the beginning of my config:
