Applications, Subnets and Multicasting Question

Hi,
 I know there was much discussions about this in the archives,
but I believe this is a slightly different issue with the subnet
and multicasting.
 I have 2 application servers running the same application on 
different subnets. This is WebObjects version 5.2.3 on Solaris
2.8. The web server (Apache 1.3.31) is on a different machine but on
the same subnet as on of the application servers. So the setup is
like this:
App server: app1.net1.x.x.x
App server: app2:net2.x.x.x
WebServer:  web1.net1.x.x.x

The WebObjectsConfig parameter looks like this:
WebObjectsConfig http://app1.net1.x.x.x:1085,http://app2.net2.x.x.x:1085
60

We had users experience intermittent "Application Not Found" errors. One
minute they'd be working, next they'd get the error.
It was corrected by making a second machine app3.net1.x.x.x and removing
the reference to app2.net2.x.x.x in the WebObjectsConfig parameter.

I thought the multicasting issue was related to running the Monitor on
different subnets in the old versions (4.5)?
