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

 Dont use GNS3, specially for calculating idlepc values, it was a nightmare
for me, once I started calculating idlepc with dynagen, it all worked out
great. Be sure to include on your config

idlemax = 100

This makes a HUGE difference!
