Dynamips crashes every few minutes

rsutton

Greetings. Has anyone seen this error message in Dynamips?


Error:
6 [unknown (0x12C0)] dynamips 5284 _cygtls::handle_exceptions:

Exception:
STATUS_ACCESS_VIOLATION
2056 [unknown (0x12C0)] dynamips 5284 open_stackdumpfile: Dumping

It is crashing about every 5 minutes and then this error comes up. I'm running 4 virtual 2620 routers on a Windows XP laptop. The laptop is only a dual core 2.0GHZ with 1GB RAM. I know I am pushing the memory limits of my laptop but I don't know if that is what is causing Dynamips to splooge.

How much memory have you configured your routers with? How much do you have free when everything's running? Does it work with two or three?

I was hitting about 850MB memory usage. It also does it with just two routers running. Here is my config file:

[localhost]
ghostios = true
sparsemem = true
2620XM
image = C:\Program Files\Dynamips\Images\C2600-IS.BIN

ROUTER R1
model = 2620XM
S0/0 = R2 s0/0
S0/1 = R3 s0/1

router R2
model = 2620XM

router R3
model = 2620XM
S0/0 = R4 s0/1

router R4
model = 2620XM
