Is there a limit of application servers you can have in a pool per the web server in the configuration.properties? I tried to see if there a hard limit. I had 4 and tried to add 6 and was getting thrown an invalid format issue when I added the final 2. All were host:port, and I didn't have an issue until i went from 4 to 6. Our load balancer handles to rotation so I just wanted to add all 6 to the pool. If there is a limit I can simply distribute them equally among the 6 web servers. I was just trying to use one standard configuration for all. There are tons of article on load balancing, but I'm not seeing a hard limit issue.
Removed the actual host name and port, but it's pretty standard.
You should be able to get a lot more than 6. When are you getting the error (invalid format ) as it is just a text document?
