The Hacki forum site has been down a lot lately. Make sure you have read
and fully understood the memory management section here:
http://dynagen.org/tutorial.htm. You'll want to look at sparsemem = true
and ghostios = true. Even then, you're likely to need to run at least
two instances of Dynamips. I can tell you that on my Dell XPS w/ 2 GHz
(non Duo) Proc and 2 GB RAM, I could never run more than about half a
dozen routers without starting to see adjacencies drop, etc (you can get
more than six router instances going, but once you start redistributing
routing protocols and the like, trouble begins to brew). I recently
followed Brian Dennis's advice to purchase a Mac Mini as a Dynamips
server and it's hard to believe how much more you can do on a non-Windows
platform with equal hardware. If this box is nothing but a dedicated
Dynamips server for you, I would definitely look into changing your OS,
as advised by others...

Subject: OT: Dynamips crashes when...

Dear All,
Sorry for the OT, I couldn't access Dynamips/Dynagen forum site (
http://hacki.at/7200emu/) today.
I am running Dynamips/Dynagen on a Dell pc with Intel Core 2 Duo
1.8GHZprocessor with 2GB RAM. I am using the new IE's workbook for
Dynamips with
their initial config and topology. I have applied idlepc value for
all of
the routers in the topology (14 routers). In the middle of
configuration,
the CPU reaches 100% and one of the two dynamips instances crashes
and I
will have to start all over again. This mostly happens when I do
tasks like
IGP redistribution, bgp sesssion peering or etherchannel. So I
couldn't
finish even one full lab.
Please help!
