Are you sure the issue is from F5 configuration and not on server configuration?

 

I already had a customer with such issue...

 

he had 2 load balanced servers and added 2 new servers to the pool.

 

the 2 new servers received only few requests. This was because new servers were configured with HTTP/1.0 and not HTTP/1.1.

 

  • without oneconnect profile, all requests from the same TCP connections are sent to the same server.
  • with oneconnect profile, each request is load balanced.

so the profile can hide the real problem and make you think the issue is in BigIP configuration.
