Improper load balancing.

Hello Folks,

 

I have a VS which is listening on port 80 and having 2 pool members listening on a custom port. I am using Least Connection (Members) Load Balancing with Cookie Persistence.

 

For some reason, all of the traffic is hitting to one pool member and another pool member is receiving very few connections. Everything was working quite well before we upgrade from 11.2.1 HF10 to 11.2.1 HF12 (engineering hotfix, to fix a bug).

 

Any idea what could be the possible issue?

 

Thank you, Darshan
