OT: Dynamips flap directly connection

Hi List,

I'm using Dynagen/Dynamips on Windows 2k machine, 2GB RAM Intel Dual Core
2.8Ghz. So far no problems, unfortunately I've tried to run two instances,
all seems ok, but I've noticed that one simple connection (two routers
directly connected via Serial interface) is flapping all time, I've stopped
all other routers (8 in total) but the flapping continues..
So i don't know why it happens... so are there some especial consideration
for running two instances... here my file:

My file to start Dynagen:

@echo off
rem Launch a local copy of dynamips
set dynamips=%CD%\dynamips-w2000.exe
cd %TEMP%
start /belownormal /min "Dynamips" "%dynamips%" -H 7200
start /belownormal /min "Dynamips" "%dynamips%" -H 7201
pause

My .NET file:

autostart = false
model = 3725

[localhost:7200]

    [[3725]]
    image = E:\IOSDynagen\C3725-AD.image
    ram = 148

    [[ROUTER R1]]
    F0/0 = R2 F0/0

    [[ROUTER R2]]
    S0/0 = FR1 1

    [[ROUTER R4]]
    S0/0 = FR1 2

    [[ROUTER R5]]
    S0/0 = FR1 4
    F0/0 = R7 F0/0

[localhost:7201]

    [[3725]]
    image = E:\IOSDynagen\C3725-AD.image
    ram = 148

    [[ROUTER R6]]
    slot1 = NM-4T
    S0/0 = FR1 3

    [[ROUTER R7]]

    [[ROUTER R8]]
    S0/0 = R7 S0/0

    [[ROUTER R9]]
    s0/0 = R6 S1/0
    S0/1 = R6 S1/1
    [[FRSW FR1]]
    1:204 = 2:402
    1:205 = 4:502
    1:206 = 3:602

CPU 50% Memory 1.5GB free.

Actually only R7 and R8 are running... and I get:

Please any suggestions will be appreciated... maybe my .net file is not
good...
