How to configure multiple instances in CF9

Question

I'm having a few issues with a couple of our staging servers that are running multiple instances of CF9, and I'm not sure if they're set up correctly. I have CF9 Enterprise multiserver installed and I created 4 additional instances using the Instance Manager. I also created a specific jvm for each one to use and reregistered each service to use the custom jvm. In Apache I added the following to each vhost (changing the serverstore and port):
<IfModule mod_jrun22.c>
    JRunConfig Serverstore "C:/JRun4/lib/wsconfig/muffin/jrunserver.store"
    JRunConfig Bootstrap 127.0.0.1:51000
</IfModule>
However, when the service is stopped for one of the sites, instead of getting the JRun 500 error it will instead return a CF error or the site will still come up. But if I stop the main CF server service it will kill all the sites.
So it seems that all the instances are still tied to the main service. Is there something I'm missing here or something that wasn't configured correctly?
I used this guide when setting it all up. http://help.adobe.com/en_US/ColdFusion/9.0/Admin/WSc3ff6d0ea77859461172e0811cbf364104-7fc4 .html
Thanks for any help.

Thanks again for the help, I think we're getting closer
So I added all the instances to the wsconfig.properties file and they all show up when I run the wsconfig.exe.

2=Apache,C:/Apache2.2/conf,"",C:\\Apache2.2\\bin\\httpd.exe,"",false
2.srv=cf2,"cf2"
2.cfmx=true,<null>
3=Apache,C:/Apache2.2/conf,"",C:\\Apache2.2\\bin\\httpd.exe,"",false
3.srv=cf3,"cf3"
3.cfmx=true,<null>
4=Apache,C:/Apache2.2/conf,"",C:\\Apache2.2\\bin\\httpd.exe,"",false
4.srv=cf4,"cf4"
4.cfmx=true,<null>
5=Apache,C:/Apache2.2/conf,"",C:\\Apache2.2\\bin\\httpd.exe,"",false
5.srv=cf5,"cf5"
5.cfmx=true,<null>
I also did this for each instance....since they were set to true.
Open the jrun_root/servers/servername/SERVER-INF/jrun.xml file for each server instance and locate the ProxyService service. Ensure that the deactivated element is set to false
But lets say I kill the service for cf2 and/or stop it in CF Admin from the Instance Manager, the site still stays up...
Here's a sample of my Apache configs.
httpd.conf
# JRun Settings
LoadModule jrun_module "C:/JRun4/lib/wsconfig/1/mod_jrun22.so"
<IfModule mod_jrun22.c>
    JRunConfig Verbose false
    JRunConfig Apialloc false
    JRunConfig Ignoresuffixmap false
    JRunConfig Serverstore "C:/JRun4/lib/wsconfig/1/jrunserver.store"
    JRunConfig Bootstrap 127.0.0.1:51020
    #JRunConfig Errorurl url <optionally redirect to this URL on errors>
    #JRunConfig ProxyRetryInterval 600 <number of seconds to wait before trying to reconnect to unreachable clustered server>
    #JRunConfig ConnectTimeout 15 <number of seconds to wait on a socket connect to a jrun server>
    #JRunConfig RecvTimeout 300 <number of seconds to wait on a socket receive to a jrun server>
    #JRunConfig SendTimeout 15 <number of seconds to wait on a socket send to a jrun server>
    AddHandler jrun-handler .jsp .jws .cfm .cfml .cfc .cfr .cfswf
</IfModule>
httpd-vhosts.conf
<VirtualHost x.x.x.x:80>
    DocumentRoot "C:/domains/cf2"
<IfModule mod_jrun22.c>
    JRunConfig Verbose true
    JRunConfig Serverstore "C:/JRun4/lib/wsconfig/2/jrunserver.store"
    JRunConfig Bootstrap 127.0.0.1:51000
</IfModule>
</VirtualHost>
<VirtualHost x.x.x.x:80>
    DocumentRoot "C:/domains/cf3"
<IfModule mod_jrun22.c>
    JRunConfig Verbose true
    JRunConfig Serverstore "C:/JRun4/lib/wsconfig/3/jrunserver.store"
    JRunConfig Bootstrap 127.0.0.1:51002
</IfModule>
</VirtualHost>
I also noticed that in each jrunserver.store for every instance, all that's in there is "proxyservers=" Should there be anything else?
